Causes Of Volvo Truck Roof Marker Lights Not Working

With roof marker lights, other motorists on the road are able to see quickly when there is a truck driving right next to them or nearby. Unfortunately, there are instances when the lights fail. 

Here are among the common reasons why your roof marker lights are not working and what can be done about them.

1. Connection is loose

If this is the issue, close your vehicle’s hood and turn the engine off. In your engine compartment, check the light assembly that you can find near the front portion of your engine compartment. 

There are screws that attach your light assemblies to the vehicle. Using a screwdriver, disassemble your light’s body. Be sure to keep the screws in a secure location since you will have to use these in the future.

Next, pull your electrical connector placed on the back portion of the unit. If your connector is loose or is no longer in the socker, you will have to reconnect it. A quick tug will let you know if the component is still good or not. 

Now, if your lights still fail to work as they should, then you may be dealing with burned out bulbs. In this case, you will have to reinstall your headlight assembly and close the hood to perform this procedure.

2. Fuse is blown

When you have a blown fuse, you will need to locate the part that needs to be replaced. Check for the location of your fuse box in your engine. It is usually found behind your battery. 

Take the fuse box lid out from your engine compartment. Then, find out the fuse that indicates the daytime running lamp, and get this out from your fuse box. When you are not certain about the location of your fuse, make it a point to check your manual to prevent any mistakes.

Remove the DRL fuse from your plug socket and install a new fuse. Then, change your fuse box cover and close the hood.

3. Bulb has burned out

If you need to replace a bulb because it has burned out, you need to get the old bulb out from your vehicle’s ignition system. Disconnect your bulb but make sure that you check the manual for the appropriate steps involved in getting this task done. 

Typically, all you need to do is to spin your bulb socket in a counter-clockwise motion, which should detach it from your assembly. Next, pull your bulb out after you have rotated the socket in the opposite direction.

It also makes sense to replace your old bulb with an energy-efficient one, so it can last longer. Reinstall the bulb and close the hood to keep it secured.

Additional Tips You Need To Know

Be sure that you have all the right tools to perform the task presented above. 

Moreover, you should use safety tools and techniques to prevent injuries or accidents since you are dealing with electricity. Turn the circuit breaker off, as well as the light switch. Also, make it a point to cap your cables correctly and mark your wires well.

If you think that the issue is with faulty connections, then you need a circuit tester to make sure it is indeed the problem and not something else. When dealing with problematic circuit cables, ask professional assistance from a licensed electrician to get the issue repaired safely and correctly.
