Blown fuse or the lights are just blown and need replacing.
Had the same problem. Found it to be a bad ground wire for the headlights. There are two ground wires for the headlights, both are directly below the battery. You can see one of them if you remove the drivers side headlight. It is right behind the radiator hose. The other is a few inches from that one.
anti theft system is bad
If the bulb is not the issue, it could be a problem with the wiring connection to the right headlight, a faulty headlight socket, or a problem with the headlight control module. It's recommended to check these components or have a professional mechanic diagnose and repair the issue.
Could be a fuel delivery problem such as a dirty fuel filter.
Blown fuse? Bad earth maybe. most likely the fuse. Fusebox located to right hand side of steering wheel. There is a headlight relay that is prone to failure.
Get it diagnosed and repaired.
Look on the right side fender (under the hood) right behind the battery, there should be a black box there with relays inside (fuel pump is one of them) and in one of these spots should be 2 15 amp fuses for the headlights. another thing to check is the headlight switch itself, take it out and if it looks burnt or smells bad that could be your problem
I have a '89 Prelude si and one of my headlights stopped working, theres a little black cap under the hood right near the light, it has an arrow on it. try turning that or pulling the cap right off and cleaning insid it. That's what I did and I haven't had a problem since.
Could this be a problem right in the body control module ??
right side low beam is burned out
The right side will have a burnt out/ missing light bulb.
A mis-wiring or short circuit somewhere between the controls, fusebox and lights.
