well i didnt install these, they came with the car so i dont know what could have been installed wrong but heres the deal.

some bumps will make my front right HL go off(de-illuminate), i turn off both headlights for a couple seconds then turn them back on and then it works again, until another bump or it will cut off by itself.

so to keep my right head light on i got to play a little game with the head lights......constantly.

what should i check for..or do i need to replace a bulb.
just throwing it out there but the headlights themselves were both upside down....so whoever installed them might have not been on the ball
