If you have a motorhome or RV with you then there is a high chance that you love going out for camping trips. These vehicles come with numerous rooms that are completely furnished. You can rest in them even while you are traveling. Additionally, one of the best things about these vehicles is that you can use electrical appliances whenever you want to.

This can be quite amazing as these motorhomes make you feel like you are traveling in your own home. Although, you have to keep in mind that there are also some issues that you can run into with these. One common complaint from many people is that the marker lights on the truck are not working. Considering this, we will be using this article to provide you with some common steps that can be used to fix this problem.

Marker Lights Not Working on Truck

1. Corroded Connection

The marker lights on your trucks or trailers are installed so that other people driving behind you can be alerted. These small lights help in keeping other drivers aware of the size of your vehicle and how close they are to it. Considering this, if the marker lights are not working then it can be quite dangerous for you to drive your vehicle.

Luckily, these can be easily fixed if your problem is just from the connector. The lights are connected to your vehicle using a small connector that consists of 7-pins. You can remove this and then observe the pins on it to check what your problem is. Sometimes these can get covered with corrosion that will cut off your connection and cause this issue. Although, if you carefully clean the connector then all of this corrosion should be removed. You can then start using your marker lights again without any issues.

2. Broken Connector

One thing that you should keep in mind when cleaning your connector is that you do not apply too much pressure. This is because the small pins of this device are quite sensitive and they can easily get damaged. Although, in some cases, the pins can break off just from the corrosion on them.

Alternatively, the pins can bend slightly which will also prevent them from working. You can simply try bending the pins back to their original location. But if they break doing so then your only option will be to replace your connector. These are widely available so you should not have much trouble purchasing them.

3. Remove Some Lights

There is a limit set on most vehicles for how much power the lights can use. Considering this, if you have been adding marker lights to your vehicle then there is a chance that the combined power from them is too much for the battery to handle.

You can easily confirm this by removing some lights and then trying to power up the marker lights. If this was your issue then you can keep on using your vehicle with a few lights removed. Although, for a long-term fix, you should switch to LED lights as these draw less power.
