I dont know what happend but all of a sudden my headlight wont cut on anymore it was Friday night i had got off work and i started my truck (ram 1500) up as usual and let it warm up and then when i was about to go to a friends house i noticed that my lights werent on, so i thought i hadnt pulled the switch but i had so i pushed it all the way in and pulled it again, they still didnt cut on, but later on when i hit a bump that night on the way home they came on so right now im tryin to figure out what the problem is because i just fixed my air suspension then this happens i work to much to mess around tryin to fix it so what should i do anyone have any shop suggestions or anything i can check. Anything helpful is appreciated greatly.
