driver headlight much dimmer than passenger headlight

Post by Shrillcaleb153 » Sat Sep 21, 2019 10:06 pm

My passenger side headlight both lows and highs are brighter than my driver side headlight, I have had to replace the socket on the driver side once or twice and I think the bulb a time or two too. How can I fix this? I want to install leds so I can actually see at night, i dont want a socket issue or something ruining my new bulbs

Check the connections. It sounds like you have a minor short, which is reducing the power available to the driver's side.

When you look at installing brighter headlights - think about the people you're blinding. You're not the only one on the road.

There may be corrosion (increased resistance) in a connection somewhere. Since headlights draw a reasonable amount of current, that may mean that connection is getting hot, and may fail soon. This may be why you've had to replace sockets. If so, I'd look for the reason and fix that. Is a liner or cover missing, allowing water and dirt into the socket?

I'd check wire splices and ground points. A volt-ohm meter and wiring diagram would be needed for this. A non-contact IR thermometer may help, too.

My wiring diagram does not show any obvious common connections between the high and low beam circuits, so I don't see an obvious place to start.

And I have to ask the obvious--is the headlight lens clean? And have you tried changing bulbs from side to side?

Could be as simple as a aging bulb OR foggy headlight lense. I would check the condition of the headlights first....if good swap out the bulb like one member said.

When replacing the socket, be sure to buy a quality socket ( ceramic sockets hold up to heat the best ). The wire splice must be soldered. Shrink tubing the soldered wire splice to prevent the splice from going bad. Use a inline splice joint and then solder the joint and finish with shrink tubing to cover.

You can check the voltage and the amp draw at each light and compare the readings. Bad connections or slice joint can cause lower voltage and/or poor current, which will cause the lamp to be dimmer.
