Clearance lights are common on Semi-trailers and taller vehicles. What they are are lights at the top of a vehicle that marks the outline so you can make sure you can clear an obstacle.
For example: Look at a big truck going down the freeway at night, see those lights at the top of his trailer? those are clearance lights. These mark out the outline of a vehicle so you can see them and so the driver can make sure if he is going under something he will clear it.
Clearance lights
If you have amber lights on top of the cab (like mine does) those are the clearance lights.......
If you are looking for an image of a clearance light, then you should go online to Google Images. It shows many different images on clearance lights as well as the source of the image.
Amber clearance lights to the front, red to the rear.
Yes, all clearance lights have to be amber. The only exception would be on the back of a trailer. Not the tail lite, but the light on the side of the tail light. This has to be red.
Your leaking at your clearance lights. You will have to take out your storage compartments above your windshield and use silicone caulk around the inside screws for the lights and then you will have to also caulk around the lights and the screw holes on the outside around the clearance lights.
Five, one Clearence light on each side and three identification lights in the middle
You have a bad ground to the from the glow plug relay to the engine block
In that case, you probably don't have tail lights or clearance lights either.Check the fuses. If that's not it, you may have a faulty light switch.
two amber in the front, and two red in the rear
On an average car, there are high and low beam lights for night driving, clearance lights on the front and back, front and rear turn signals, and back-up lights used when backing up.
By "exterior" lights I am forced to assume that your mean the tail lights, brake lights, license plate lights, and if available, the side marker and clearance lamps. When a trailer light wiring harness is attached to a towing vehicle's electrical system, it is generally tied into the tail/brake/license light wiring harness. If that is the case with your setup, then the same fuses that serve the vehicles light system[s] also serves the towed vehicles lights. Usually, one fuse serves the brake lights, and another serves the tail, license, side marker, and clearance lights.
