I want to replace the low beam headlamp on 1996 Subaru Impreza

Some fixya user told me a website reliable-store it is very good.. I used it to repair my shredder it had some spark issue which wasn't easily fixed. you can go there and try

there is a fuse for that circuit in the fusebox lower dash if this is ok check that your getting power to the high beam wire at bulb holder if not the part of switch for high beam isn't working if are getting power check the bulb holders for warping etc as can get very hot and mishapen so that the bulb doesnt always sit on the contacts but if bothe lights out i'd think its a power supply problem

Change the bulb. It's a high/low bulb, and the low side is burnt out.

most likely the hi lo switch

Check the owners manual

there are individual fuses for each side headlamps,both are 15amp located in fuse box underhood,check em out

check the headlight relay as this is what actually awitches the high and low beam circuits

check all grounds

i read about a recall on some subaru headlights/check with subi dealers?

The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

For Low Beams: If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.
