Test and make sure you are using a known good bulb & fuse.

i just noticed that after fixing the headlights that the highbeam do not function. i tested the bulbs and they are good. was just wondering what i should check next....

[danielsatur]

Do the bulbs have two filaments?
One for the low beam, the other for High beam?

[rolla1]

The bulbs i have only have one filament in them...

The resistance of corrosion can cause the bulb to not work, clean sockets, and use a bulb grease for protection.

whats a good cleaner to use so that i don't damage the socket?

CRC Electrical cleaner.
Make sure, your car doesn't require a two filament bulb!
