My lights on my 2005 RR L322 87k miles have gone crazy. I can disconnect battery but no fix, fuses have been checked in glove box and in rear all appear good. The headlights wont turn on but the passenger side repeater stays on. Both fog lights not coming on, no blinkers and NO brake lights. Any thoughts would be greatly appreciated. Car is in great shape but no lights working. Thank you for any suggestions.

I presume you have checked fuses 9, 4 and 53 on front fuse board and the links 3 and 4 each rated at 50A.

checked 4 and 9 but not the others. I will check per your suggestions. Thank you

3 and 4 in the rear / boot ?

Links 3 and 4 are to the right hand side of the fuses on the front fuse board.

I will check all 50 amp fuses / thank you

Pretty certain it will be caused by a faulty lighting control module. It’s easy to access from behind the panel at the right hand side of the accelerator pedal. They frequently give problems this time of year due to ingress of damp.
Sometimes they can be fixed by dismantling and drying out. Otherwise you can send it off for a refurb for about £40-50

Sorry, just notice you are in the US. I was referring to a rhd UK car. In you case it may be to the right of the passenger footwell.

I believe you are correct / do you know who can refurbish a LCM ? or what kind of shop should I look for in the US ? Thank you

In the UK there are several people advertising this repair service on eBay, so I would check there first.

I will check EBAY / I found a refurbished for $175
