A good way to protect the cab of your truck is to keep bright clearance markers on top. It benefits both your vehicle and any vehicle looking in their rear-view mirror. Most states require vehicles of a certain size to have cab lights. Their purpose is to let oncoming vehicles know the cab size of a vehicle in the oncoming lane. You are required to have cab lights on your truck for anything over 80″ wide. Also, vehicles with trailers under 80″ wide can use cab lights to let other vehicles know they have a odd-shaped or sized trailer. Most large, diesel, medium duty trucks use some form of cab light. Cab lights always have to be amber and will never project light any other direction than forward. Red lights are reserved for the back of vehicles to show that you are traveling in the same direction.
There are many different styles of cab lights; we have watermelon LED cab lights, torpedo cab lights, cheap cab lights for your truck, or 17 LED cab lights. We have them both with amber and clear lenses with varying amounts of diodes. If you manage to only bust a lens on an existing light we sell replacements for those as well. We can also replace broken visors for the lenses. Don’t let your truck get busted by the DOT! Replace any broken lenses or lights on your semi immediately. We sell them in kits of five for a complete redo, or individually. I’ve included the link here to the DOT’s regulatory page for lighting on commercial vehicles. It should be a good resource if you are unsure about what lighting you need for your vehicle. It goes on to explain about headlights, cab lights and tail lights for both buses, trucks and trailers. Style aside, truck cab lights are a very important edition to your vehicle.
