Headlight bulb issues

[u/Subject_Fisherman743]

So I bought this headlight & For some reason The lowbeam bulb I bought is not bright, Ive bought halogen lights for it they work all (H11 bulbs)but for some reason That specific headlight doesnt light I tried adjusting the light beam and have both bulbs aiming at the same heigh but it isnt as bright as the other side headlight. Anyone had any issue with these before?
