83 C10 Headlight Issues [HELP]

[Bo69]

Installed aftermarket headlights and now only bottom two come on see picture, previously all except for bottom passenger side came on which I had assumed it was just burnt out but now suspect possible wire issues. What do you guys think is my issue? Also how do the brights/low beams work on these trucks? My not knowing how they work may be the whole issue. Any help would be greatly appreciated! One pic shows when I only had one side done both of the new ones came on but after finishing up and doing the other side only the bottom one on both sides comes on.

Aftermarket lights, call for an adapter.

First of all you should have found out why your lights weren't working before you started replacing things now you/we don't know if it is a preexisting problem a new problem or 2 problems. Have you read your instructions thoroughly? Read them again thoroughly just to make sure you didnt miss anything. I pissed my boss off at work one day he put a plow and light kit on his truck lights didn't work right afterwards. I asked, did you read the directions. WTF is that going to tell me a couple hours d!cking around trying to figure it out he read the directions and can't remember what it was but right in the direction was something that wasn't obvious would cause a problem but the manufacturer had crossed that bridge and had the answer.

Thank you both, I should have read the instructions lol and now I will (if I can find them). I just assumed the light bulb was burnt out and that the problem would be solved by the new headlights but that is what I get for assuming!
