Hey all,
Just trying to work out how best to test, or what a likely issue is.

I have a 2007 L322, it already had for 2010 led headlamps when I bought it.

The passenger side lamp has always been a bit problematic. Would turn off if I braked too hard, but turning off/on fixed them.

But now the halo/fairly lights arnt working at all, neither is the indicator.

Main and high beam is fine, and no issues at all on the drivers side.


Where would I even start to diagnose?
Odds of the passenger side unit needing to be replaced?

Thanks

Got the bumper off and tried a new headlamps unit. Still not working.

Can anybody make head or tails of the wiring job?

i can only suggest a forum search to find any headlight/upgrade conversion threads ...these should give you an insight of how the were fitted.. ... - .- -.

Thanks. Ill take another look through in a bit more detail.

But the only ones i could see, the images weren't working, and no mention of electrics.

Most conversions I see use the PowerfulUK conversion loom and 1 ballast.

I havnt seen ones with 2 ballasts and 2 relays per light.

yes some pics are missing unfortunately....some members have done conversions themselves so hopefully might be able to help..

are there any youtube videos? ... - .- -.

Finally found this video from powerfuluk



But no reference to even needing a relay 🤷‍♂️

Just a diagram for from > to, pin connectors

is this any good,
