It's the simple things that bite me the most, like splicing the ARB lights into my current lights. The extra load causes the blinkers to dim dramatically and blink too quick. If I remove the bulbs from the factory blinkers the ARB lights work fine or vice versa. Or if I turn the light switch on they all work (but easy to forget during the day.) I even replaced the flasher but the problem still seems like a load problem. Has this happened to anyone with an older ('92) XJ?
