Have any of you replaced the headlight buld, if so, please explain?

 

Another member posted very detailed instructions with pictures for DIY replacement, but I cannot find it right now. Try search.
Or are you asking about the Dealer doing it?

 

The high beam replacement isn't too hard, but requires delicate little paws on the driver side to fit in there. There's a thread in the main RL forum with the terms "Lighting Upgrade" in it, and I've posted some info about doing the swap there.
