Upgrading led / brighter bulbs thread
I just wanted to start a thread consolidating all the upgrades to led or brighter bulbs for our vehicles.
I know with the advent of led bulbs and the use of canbus systems it can sometimes be a hit or miss with what works.
My goal in choosing a replacement bulb is to always find the best oe comparable solution, meaning no worries, no errors and no faulty lights. It has to be plug and play and work.
All my opinions are my own and I'm not being compensated to give any of them, only hoping to share the knowledge with this forum.
H7 halogen projector bulbs.
For those who don't have the xenon from the factory I think it is best to contact Azn optics to install a retrofit hid kit. It's plug and play, will fit in the projector housing and you will have the lighting power and blue xenon colour and brightness that you were supposed to have to begin with.
I'm really disappointed in mercedes that they didn't spec our gl with xenon headlights standard from the factory even on new gls models. It is downright embarrassing in my mind and I cringe when I see other mercedes products in the road with halogeen headlights.
Xenon hid bulbs. Standard on 550 models optional on all other under lighting package
I tried the d1s philips oem standard vision bulb. This is a cost effective option. It does what it needs to do. It is the standard replacement bulb for most oe spec vehicles.Philips D1S Standard Authentic Xenon HID Headlight Bulb, 1 Pack (85415C1) https://www.amazon.com/dp/B00CAV7T56/ref=cm_sw_r_cp_api_ERaaCbTQ14GPG
The bulb I would recommend and am using myself is the Philips xtremevision gen 2 d1s bulbs. These are really amazing and the light is white and crisp. Everything is much brighter and now in winter time I often don't have to use the brights and more because of how bright these bulbs are.
These should probably be replaced around the 5-8 year mark.

Reverse light bulbs
I ended up wanting/needing better reverse lights to help with the inadequate lighting when reversing to help the rear view camera operate better at night. Also having brighter reverse lights in my mind gives me an extra feeling of safety knowing that I would be hard to miss when reversing.
I'm very happy with these bulbs. They're all really bright look well designed and have a very attractive design and thought about heats ink. I have had no errors or issues whatsoever.

Parking light front bulbs
I used these bulbs from yorkim. I wanted to match the blue colour from the xenon headlights instead of the atrocious yellow colour parking light bulbs that are always on with the headlights. So far im happy with this brand. I tried a different brand that would burn out within a week so I returned those.
These give no error and so far work great and theyre quite bright. The best way to get them out is with a pair of needle nose pliers with a minimum length of 8" once you got the hang of it it should take 2 minutes and save close to 80$ when compared to the dealership

I have not found a reliable led replacement for the turn signals inner and outer nor a proper replacement for the h7 brights.
Any other recommendations and findings are greatly appreciated!
Hope this helps some people!
update: new license plate bulbs 💡
New license plate lights that work without errors or issues. Be sure to order the correct fitment according to what is on your vehicle. The curved or square license plate light. Gas models may have the curved version listed as diesels, diesels may have the square version listed as gas only. Be sure to check your car first.
If it curved, go with the link that describes itself as diesel ones only.

For the small "city light" I went with a white Phillips. I also went with Phillips on the reverse lights.
I'd like to somehow integrate small fogs in the bumper with the already factory led strips.

I also did the brake (one of the pair) and backup lights. For each of these I added parallel resistors to eliminate the CAN bus errors. Again, a lot of work, but I'm happy with the results. Particularly the backup lights; not only are they now actually usable for illuminating the rear, they are much more useful for telling other vehicles that you are backing.
I did LED replacements on the "parking" lights, but it was a charlie foxtrot of the highest order. I gave up and will go to applying the effort to something more useful, namely the amber corner marker lights. I'll move the load resistors to those and put in amber LEDs.
Hit me up if you want info on any of the above. I should post a picture of how I installed the load resistors on the rear modules.

I wonder if the '10 has more tolerant software on the CAN bus. If not, I'm real curious what your bulbs are doing with the extra wattage they're dumping as heat. With a load resistor, at least you're getting that heat away from the socket, etc. The excess heat shouldn't be a problem, because the peripheral lights are only on for brief periods, but still I'm curious.
It's pretty stupid that by '07 the MB engineers didn't anticipate people installing low power consumption replacement bulbs.
My high beam H7 LEDs are fantastic. It's unreal how much light they throw down-road.

I'll check 'em out, though. I've already got the load resistors; I just have to move them to the other circuits.
Although they shine bright as the sun, it still causes an error message on the dash saying the bulbs are out.. Any suggestions?

A little education for everyone: The system monitors the current flow through each light circuit. If the current flow drops below a certain value, say 50% of nominal, the system alerts the driver that the bulb is out.
LEDs make about 8x as much light per watt as filament bulbs.
Typical LED retrofits run about 1/4-1/2 the wattage of the filament bulbs they replace. Therefore they make about 2x-4x the light. You could make them the same wattage, but LEDs have a problem with heat - and they're already bright as the sun.
The LED makers go to 1/4-1/2 the wattage instead of 1/8 because people like bright, and people will be less likely to have bulb-out errors the higher they push the wattage.
Some bulb makers build extra wattage dissipation into the bulb housing. That's why some of them are bulky aluminum. That's not a super nice way of doing it.
My LED headlights have little aluminum boxes in line with the bulb; this box dissipates the extra wattage safely away from the bulb.
For the smaller bulbs, the solution, if you're a nerd like me, is to measure the filament bulb current flow and the LED current flow; subtract LED flow from filament; figure out the resistance you need to dump that extra current, and the power rating of the resistor you'll need for it. You order that resistor from China (or locally, if you're impatient and don't mind spending a few extra bucks), wait a month, and when it arrives, wire it in parallel with the bulb. That's the right way to do it.
I do not know how the %-of-nominal figure is settled on. DOT mandated? Also, some systems, MB included, will test bulbs with pulses of current, so the bulbs "flash" before the system figures the bulb is hopeless and quits trying.
My guess is your license plate lights run pretty high wattage (bright as the sun), but still low enough that it triggers the error. I think you're sierra oscar lima unless you want to stuff a resistor up there somewhere. It's not what I'd do for mere license plate lights; I'd send 'em back as not actually being CAN bus compatible.
Hope that helps.

Replaced the high beam with LED and they're fantastic. But nothing can be done to the low beam that I know of. I'm thinking of adjusting our high beam angle down so they can be used as low beam without annoying oncoming drivers.
I have a Ford pickup. Replaced the halogen bulbs in the headlights and both low and high are fantastic. It's a shame that Mercedes can't match Ford. But it doesn't in so many ways. Our next family car will not be a Mercedes. Too much money for an inferior product.
Say what? Yes, it's harder, but they're both H7 bulbs. The low beams are flipped 180 - upside down relative to the high beams. I lived with the LEDs in high beams only because working on it was such a pain, but I finally got to the bottom of it. They work great. I literally had to grind off aluminum from the end to get rid of a center dark spot on the low beams, but even that was elective surgery. It can be done.
So help me understand: What good did you think it would do to come on a Mercedes forum and whine? No one wants to hear it. People are here because they like the cars despite their quirks, or they have them and, like with a fetal alcohol syndrome kid - which you might want to get checked for - have decided to make the best of it. I spent a bunch of time hating the GL, but I dunno ... I worked the bugs out and kinda got used to it. I took it off road and got to thinking it's kinda cool. It is what it is. Sell it. Or don't. But don't whine about it.

Here is what I used....really bright and no error messages

Below are my solutions for the turn signals, reverse lights, and front parking bulbs......once I get the parking bulbs in, Ill report back findings. I have the turn signals in, but I am waiting to get my H7 High beam Bulbs, Reverse bulbs, and Philips parking bulbs in before I tackle the exterior lights.

Plug and play? Looks awesome and better than replacing just a bulb.

Nice!
Do your turn signal bulbs flash? Are they cool ❄️ enough? No errors? ⚠️
Your parking light bulbs will most likely give errors. They are the Philips ones? The bulb needs a canbus resistor to not get an error. Try the one I linked if it doesn't work out. EBay is always difficult with returns so j like using amazon.
The osram cbb are well reviewed and liked. Look at some of the comparison videos between the cbb cbi and philips xtremevision and white vision bulbs to see what you like best.
I liked the Philips xtremevision best. Ymmv
On the Philips parking light, yes they are Philips....Hmmmm....still waiting on them, but if they throw errors, I bought some extra Canbus T10 LED lights, so if they throw off a error will swap em.
Good to know on the back up lights, but they too are Canbus.........guess Ill find out too....LOL.
Thanks
