Last year I installed my Watsen signal lights and I love the looks of them. The only downfall was that with Watsen signal lights you have to loose your running lights. A couple months ago I noticed that Bayside Performance carried $15 modules that turn your Watsens into running lights.
I installed the lights, last year, myself and also the little resistors that make them blink slower. But, wiring in the new modules turned out to be a little bit too mutch for this boy. I tried and tried and gave up. ( Yes, I did)
I left it a couple weeks but, finally today, $75 of shop labor later, I have running lights again.
