Ok I did my conversion yesterday from autoptiks. I ordered some bulbs from a different place, the bulbs were Wizzard's or something like that. Drove it last night and the are dimmer than my old one's /forums/images/graemlins/angryfire.gif DO NOT BUY THESE BULBS!!!! /forums/images/graemlins/angryfire.gif The reason I ordered these is b/c I had done the conversion on my old 71 C-10 from the same company and thought that these were the same bulbs. The one's I used before had a rainbow coating on them, kinda like you poured oil and water on them. Well the new one's are just a medium blue. SO, what bulbs have ya'll had success with? /forums/images/graemlins/ears.gif I've heard good things about PIAA's but they don't list them on their website. I have found them other places and on ebay though.
