Hi guys. The headlight lenses on my vehicle have turned yellow again, I’ve replaced them before and have used the UV protection as well. This time they have started yellowing from the inside.

Knowing the quality of aftermarket lenses I’ve decided to just replace the headlights. However I can’t seem to find the right headlight assembly anywhere.

I do find the headlights for option 615, active cornering available at multiple sellers so was wondering is it possible to use option 615 on a 614 car, I know coding would be required but would I need to change the harness, modules etc.

or is my best & easiest option is to update the projector(improve light since I already have the headlamp open) and get new lenses ?

vehicle info:
03 E55 (07/2003 production date)
Option 614,
headlight part numbers A2118201761 (Left) & A2118201861 (right) is what I get from EPC.

 

Finding active lights that are actually active will be hard. Many online may be listed but will arrive as standard. Coding them to work is simple if not currently present.

As for a projector swap sure makes the biggest diff but with old lights moving the wires the insulation will fall off. You will need to take time to recover, rewire and plan for new lights.

here is a thread from 21 I did swapping in Morimoto projectors on brand new OE active lights.

Thank you sir for saving my day.
