Automobile modification has become an increasingly popular pastime across the world. A popular modification is the addition of under-glow, lights affixed to the underside of the car to cast light onto the street below. Installing an LED under-glow kit can be done by a professional, or at home.
Disconnect the vehicle's battery.
Find an installation site on the underside of the car. This site should be away from any fuel lines, exhaust systems, moving parts, areas that heat up, areas where a spare tire is accessed, or anywhere that a lift jack is used to raise the vehicle. Ensure that any holes drilled won't interfere with or cut off these areas.
Raise the vehicle up on a jack and test fit the LED light tubes. Find a location to mount them that aligns with the diagrams and instructions included in the under-glow kit. Ideally, they should be mounted so that that they are centered with the vehicle's overall length, and positioned on the chassis so they aren't visible.
Place the mounting brackets included in the kit on the tube and lift the assembly into place. Mark where the holes in the brackets line up on the chassis with a pencil or marker. Set the assembly aside.
Using the center punch, punch out the markings.
Apply a small amount of silicon seal to the holes to protect against rust.
Insert the screws into the LED tube assembly brackets, and hold the brackets up to the holes in the chassis so they line up. Tighten the screws into the holes enough that they hold the assembly in place. Ensure wiring from tubes on the side assemblies come out to the front to ensure easier wiring to the distribution block.
When the assembly is in place, tighten the screws with your power drill's screwdriver until they rest firmly in place and won't move. Repeat the process for each LED tube assembly.
Identify a mounting location for the distribution block, ideally a flat surface, high inside the engine compartment. Mount the distribution block away from moving parts or extreme heat.
Connect each tube to the outputs on the top of the distribution block.
Find a location inside the vehicle for the LED under-glow system's control panel.
Hook the ribbon wire from the control panel to the distribution block, through a hole in the engine compartment's firewall.
Connect the control panel's power wire to the positive terminal on the car batter. Attach an in-line fuse no more than 18 inches away from the battery. Attach the control panel's negative ground wire to an existing negative ground wire, or screw it securely to the chassis.
Lower the vehicle back onto it's wheels, reconnect the battery and start it up.
