When I bought my truck 3 years ago, when you hit the bright light switch, the low beams would stay on and the high beams would also come on. I think the low beams were dual beam lights. Well the low beams burned out a while ago, and the replacements turn off when I hit the bright lights. The lights are model #4656, which is what was called for in the application guide at Kragen. Am I stupid or is there a different light I can buy to have my four beam setup back, I don't want to mess with wiring if I can get the right lights. Truck is an 82 K20 w/the quad headlights.
