If you own a huge truck or a trailer, chances are that you've thought about installing a cab light assembly. As a matter of fact, in some states, cab lights or clearance lights are required on a vehicle that's at least eight inches wide. This is to make sure that oncoming motorists will clearly see your vehicle and the huge load behind it. If you're planning to install one on your vehicle, here are some tips to make the installation hassle-free:
Set aside a lot of time for this task.
Installing a cab light will require you to remove plenty of parts that include the passenger pillars, visors, and overhead display lights. Depending on your car make and model, the list could be longer. This is why it's best to set aside several hours for this task. If you're a very meticulous person, don't be surprised if you just spent five hours of your day finishing this installation.
Get your measurements right.
Getting the right measurements for the cab light assembly is probably the trickiest part of the installation process. One inch off can lead to unsightly holes on your vehicle's roof, misaligned lights, and not to mention an annoying leak caused by a poorly drilled hole. So before you drill any hole on the roof, make sure you have figured out exactly where to attach each lighting fixture, how far each fixture is from the others, and the distance from the cab roof's front end. To get the measurements right, equip your toolbox with a measuring tape, ruler, a wet marker that can easily be erased with water, a pen, and paper.
Choose a wiring method you're most comfortable with.
The next trickiest part of the installation process is the wiring of a cab light. Once the lights are properly wired, switching them on and off is a breeze. Keep in mind that a poorly wired electrical system can easily lead to short circuits, blown-out bulbs, and lights that won't switch on at all. Since there are several ways to wire a cab light into your vehicle's electrical system, choose a method that you can handle based on your wiring skills. Depending on your chosen method, you can use butt connectors, wire nuts, or a soldering tool to connect wires.
Seal holes with the right product.
No matter how precise you are at drilling holes, these holes can, when left unsealed, lead to annoying leaks that can cause serious roof damage in the long run. This is why you need a waterproof silicone to seal these holes up. When applying the silicone, make sure you're applying it the right way and you're using just the right amount; enough silicone should be applied on each hole before the screw is tightened or locked in place. Before you grab the first tube of silicone you see, read the label first and see if it's designed to withstand regular exposure to damaging elements. You can also check out online product reviews to figure out which product is worth your money.
