1) bad bulb - try switching them
2) bad ground
It could be a bad bulb, a bad ballast, or a bad ground.
on our 99, i have to remove the headlite assembly to get to the horn. there is one on each side
Fuse is bad for that side.. Check it, under the hood fuse box. Just fixed mine.
Headlights have two filaments, one for dim, one for bright. From your description it appears that one of the high beam filaments is burned out. Replace the bulb.
The bulb that glows brightly likely has a higher current passing through it compared to the dim bulb. This could be due to differences in resistance, voltage, or power ratings of the two bulbs.
A dim headlamp on one side could be due to a few reasons: a faulty bulb or LED, a poor connection in the wiring, or corrosion at the contact points. If the headlamp uses a lens, dirt or moisture buildup could also affect brightness. Checking the connections and replacing any damaged parts can help resolve the issue.
You change the bulb for the right headlight the exactly same way as you changed the left only opposite. If you are replacing one headlight, even if the other still works it is best to replace them in pairs, for lights can dim and if you have a bright bulb and a dim bulb you could be in danger of distracting other drivers and causing an accident.
Check for bad grounding of light socket or the wrong light bulb
not very long.. they are really crap... i have one and its very dim...
In a lamp you can have three settings with two filaments. One filament is for dim. When it is on, the bulb is dim. One filament is medium. When only it is on, the light is medium. When both filaments are on, the bulb is bright. In auto and motorcycle applications headlamps can have 2 filaments. A 'dip' beam and a 'High' or 'Main' beam. When the High Beam is on the Dip is off and vice versa.
Check ground circuit Make sure bulb is not burned out
