RJ Automotive MERCEDES MULTIBEAM INTELLIGENT HEADLIGHT PLUS ACTIVATION - US/CANADA

Has anyone in the U.S. performed the headlight modification in the subject above using RJ Automotive? It looks like RJA has lots of interesting mods, not the least of which is to the headlights.

I've gotten quite a few done and they were all a success:
1. Change Bluetooth SSID
2. Full individual drive mode settings unlock
3. ECO start/stop remember last setting
4. Race mode
6. Sport+ as startup mode
7. Parking damage detection
8. Car wash mode
9. Energizing Comfort

Not for an E-Class model, but the same applies to a wide range of models. if your E-Class doesn't have MBUX, there will be some things that will not apply.

Just look over this page to get an idea of what you can get done.

Thanks, Eaton. I have a 2023 E450 so I think I can do most of those things. I'll check out the link. Thanks!

I have a 2018 E400 Sedan and a 2019 E450 Coupe. I used RJ Automotive to perform the headlight modification on both cars. They were excellent and the lights work as they do in Europe. Took about 15 minutes or less and was painless. Would recommend them any day.

Curious -- does the headlight modification have on "on/off" setting or once RJA programs it, it's "on" permanently?

It's a 2023 e450. Is there a change in 2024 MY MBUX that allows the option to turn it off?

I used RJ Automotive to do the headlights on my 2017 E300 and 2018 E400 and I could not be happier with both the experience and the outcome! I highly recommend using them.

Question: I have a 2023 E450 (U.S. version). Two of many listed Mods on the RJ site are listed below. My E450 has not been modded, yet I do have working auto park assist and lane change. What exactly do the mods shown below do that is over and above what comes standard with the vehicle? I've googled the UN-79 regs and impact on Mercedes, but it seems incongruent with my vehicle. Thanks.

17. Automatic Park Assist re-enable - 3 Credits
• If your car was built after Nov 2020, due to the new UN-79 Regulations manufacturers have had to turn off/reduce Automatic park assist. We can turn the full park assist back on.

18. Renable Automatic Lane Change Assist- 2 credit
• Re enable the automatic lane change assist which was disabled due to the UN-79 regulations. Your car must have the driver assistance pack for this. This changes lane automatically when pressing the indicator.

These regulations do not apply to US vehicles so you do not need them
