I just recently purchased an 88 cherry red dl wagon in great shape and was wondering if anyone knows where I could get an IKI high beam headlight assemby for the passenger side. Three out of the four lights are IKI which I believe to be the original lights. The other is a sylvania that looks like crap, it works but its all dark and burnt out looking. The numbers on the high beam assembly that I do have is RW160. Ive tried finding them myself through the internet but have had no luck. Thanks for reading help me if you can.
