hi all,

i havea 93 civic dx with a very bad headlight bulb. driving at night feels like that my headlights are off!!!! any suggestion on what type of headlight bulb i should replace it with. what type of headlight bulb are you guys using???? i like the one that looks like white clear but not sure which one will fit mine. thanks!!!

 

H4 if you have stock headlights

 

heard some good things about the sylvania silverstar or sylvania silverstar ultra's. HID's would be another option.

 

sylvania is over hyped, just get generic oem replacements for factory housings, if you need more light, then go h.i.d or fog lights

 

consider cleaning your lenses too. i had the same problem before because of the reflector cap seems to have corroded therefore its showering powdery deposits on the chrome relector; this in turn affects the light output. you can remove the glass by heating it up to dry the sealant (there's a diy about that in this forum somewhere. just search it) and just pry it off. the insides of the glass might have clouded up to. reinstall them by putting silicone sealant around the glass and reinstalling them. if they have the clips, put them back too.

i have since switched to hids but after the initial cleaning, the illunmination from my stock h4s really improved.

 

When the reflective coating on the back of the housing has gone bad, the bulb will light up but won't throw light down the road like it should. Changing the bulb won't help. A new housing assembly is probably the only cure.

 

What about deposits inside the bulb itself; I have a brown murky coating inside the 9005 bulb. The bulb works, good light output. My issue is the right DRL/high beam points up. The low beam is good, but the DRL/high beam points up and low beam is normal. Since the HL assembly is one piece, with one adjustment any ideas? The bulb is correctly mounted, as is the headlight assembly. Could this murky substance be causing the light issue, ie bending the light?

 

Replace that bulb. The filament can get out of alignment inside the bulb and then the beam goes the wrong place.

The problem could also be on the low side, causing you to tilt the whole assembly upward to compensate, with the result that the high beam is now too high.

 

I'll give the bulb change a try; It looks like the bulb was underwater, and when the level went down, the rusty water residue was left inside.
