My honda prelude's tail lights and parking lights stopped working suddenly. The head lights, brake lights, reverse lights, turn signals, and four way flashers all work fine. Its just the tail lights and parking lights that dont work. They have come on a few times since they went out, but they just go out again after a few minutes, and all the fuses are good. That's why im thinking its a relay, but I cant find a relay for the tail/parking lights. Its not labeled on either of the fuse boxes.
Anyone know if there is a tail/parking lights relay, and where I can find it on a 93 prelude?. And maybe what it looks like?

It would seem more like a bad connection, remove the bulbs and look for any sign of corrosuion, (greenish) goo in the sockets and connectors. You also need to inspect the ground wires...

But all eight of the parking/tail lights have gone out. Would that happen if it there was corrosion in just one of the bulb sockets? Also, this happened right after I smelled a strong electrical buring smell in the car.
Just out of curiousity, is there a relay for these lights? And if so, where can I find it?

There is an integrated control unit next to the fuse box, but if the tail and parking lights are out, suspect a wiring problem...

I am having trouble uploading pictures right now, I will try again later. But the control unit does the flashers, oil pressure warning and other stuff, if these work I think it's wire or fuse related.

Ok, so just to reiterate, there is no relay for the tail/parking lights, right?
Although i've checked all my fuses, and they're all good, I can't seem to even find a fuse for the tail/parking lights!
And if it is wiring, where would the problem be if the side, tail, and corner parking lights are all out?
Thanks.

Brodland, I know exactly where you are at. I could list everything on your car that doesn't work due to your situation.

Step 1:LOCATE/TEST/REPLACE IF NECESSARY with a 20AMP fuse, FACTORY LOCATION FUSE NO. 42
(this fuse is located under the hood, toward the back of the ENGINE BAY [passenger side and to the back left side of the engine compartment], inside a black fuse box with a easily removable cover)
can also be located in the pictures/schematics posted by a previous responder

-I found that mine was fine-

Step 2:

Test/replace COMBINATION LIGHT SWITCH
(that is the repair denotation of the entire turn signal switch)

-I found that mine was fine-

***IF YOU GET TO THIS PONT***
If you get to this point and have not found a resolution, then you and I have the same problem.

You have a SHORTED (connection to another signal-ground or hot-) or an OPEN (break in this connection) SIGNAL/CONNECTION)

You and I are going to be looking for an abnormality in the wiring/connection plugs

Our signal runs from the NO. 42 FUSE to the COMBINATION LIGHT SWITCH > to a junction where our signal is split into an additional signal
From this junction, one signal runs to one tail light, and the other singnal runs to other multiple locations
If our problem gave us one tail light working while the rest of our original symptOms remained, the we would be looking for our OPEN between this junction and the problematic tail light and the rest of our components which have malfunctioned

HOWEVER, we are looking for, either an OPEN signal between our COMBINATION LIGHT SWITCH and the junction where our signal splits first, or a SHORT between our COMBINATION LIGHT SWITCH and and any of our seemingly malfuntioning components. Also, these components must have the signal introduced to it directly.

-this is where I am at currently investigating the same issue-

Good luck!

I had this problem. Still kind of do. Read this post and it helped me through my search. My problem was a loose wire in the plug where the harness hits the under dash fuse box. Tension on this harness over time loosened the wire in the plug. I need to get a new plug from the junkyard( well used) until I find one I just put tension the opposite direction and wrapped it with electrical tape. If it flickers out I just push in on the plug. Hope this helps anyone who comes across this.
