The Lubbock Police Department based in the state of Texas in U.S. published a guidance list to installing aftermarket automotive lights on their Facebook fanpage, reported 790 KFYO News Talk.

Budding automotive lighting market in U.S. contributed to the surge of these products popularity in personalizing cars, and adding a bit of flare to the modified cars.

However, there are certain limitations to what kind of color, number, and height of lights.

According to the published statement, only authorized emergency vehicles, school bus or tow truck can use white, red, or blue lights that flash, strobe, or beacon. Red lights are also reserved for rear of vehicles, and under no circumstances should be placed in front of the vehicle.

No more than four lamps can be displayed on the front of a vehicle at one time. A car with headlights and fog lights is fine, but adding a grille light would be illegal. Even though LEDs are made up of rows of tiny LEDs, the row or housing of LEDs is counted as only one lamp, instead of calculating the individual LEDs.

As for height restrictions, the auxiliary lamps has to be placed between 16-inches and 42-inches from the ground, and the fog lamps between 12-inches to 30-inches. A vehicle with a LED light bar mounted on top of a truck and operating on a public roadway, would be considered as a violation of height restrictions.
