2013 C250 HID Install
Stock halogens

Stock connector turn to remove

Stock connector removed

Stock halogen bulb attached to connector

Pull bulb straight up and out

Once bulb is removed

Use flat head screw driver to remove metal clip from plastic connector with wiring

Drill a whole into stock dust cap for wiring to fit through

Depending on what type of HID kit you have, you will need to manipulate the wiring harness to fit through the opening of the stock metal clip and the dust cap. I had to pull apart the wiring harness wire by wire to get each wire to go through the metal clip and dust cover.

If you can get the base of the hid bulb and wires through the opening of the stock metal clip, the reinstall is the same as the factory setup no need to modify anything

RED (+) into slot with one wire, BLACK (-) into slot with two wires. After this pic was taken, I used electrical tape to secure the wires onto the connector so they don't come off.

Plenty of space inside the housing for all the wiring. Air tight seal with dust cap back on

HID H7 bulb flushed with housing inlet. Location and ways to mount the ballast is a personal preference so I'll leave that up to you.

Done!



HID much brighter than stock halogen

Halogen cut offs

HID cut offs, not too much glare

I wanted to get a car with lighting package but couldn't find one at the time.
If the oncoming traffic flashed their high beam at night on you, then I assumed you prolly know what it means. Cars fitted with HID on a non-projector beam always get the blame for head on collision at night.
Just my 2 cents.
Btw, did it throw error code after the mod? Can't do just that on a Bimmer!

Blamed for head on collision at night because of aftermarket non projector hid?

No error code with the error code eliminator

. I have the 35W kit and the hid bulbs are similar length to the stock halogen bulbs. I don't know about 55w kit. I did not purchase the mounting brackets, I used zip tie.I have the error code eliminator, I don't have any extra wiring harness.
Check out this site: www.hidplanet.com. You have a $40k car, do it right.

Do you have pics of retrofitted HID bulb + projector so i can see what the difference is?

Thanks for this, just fitted 6k's on the mrs w204 projectors,they light up great and controlled but I like things tidy so the ballasts on the inside is far more secure and out of sight.
I understand why you centrally mounted them as to me it's just a ..looks right kinda thing but not every one will be that fussy
I nearly screwed up on the drilling as I just took 1 inch is the whole size but then checked and the inner ring on the grommet was 3/4
but all done and the guide was a great help thanks
