hey guys is it possible to put rx400 led tail on rx350?
need to do some wiring like add relays or resistors? or just bolts on plug and play?
the Led looks very cool at night!

 

I am not sure. The light itself should just bolt right on. However, you will probably have to splice some wires to make the lights work. You may need resistors, for the RX does have a warning light if one of the tails are burnt out. I wouldn't think you would need any addition relays or anything, but I don't know how exactly it is wired. I haven't seen anyone do it yet, so keep us posted.
