The Installation of Neon Lighting
August 30, 2011 Category :Decorative Lamp 0
Of the many car accessories on the market, the most attractive are neon light kits that install under the car. They come in many colors and draw attention to your ride. The installation of these kits is simple but requires attention to detail. A high voltage power supply is provided by an auxiliary transformer installed under the car to power the lights. To avoid any problems with the authorities you should install a switch to turn the neon lights off or design the system to only turn on when you flip a switch inside the vehicle.
Disconnect the negative battery cable to remove any power from the electrical lines in your vehicle. You will need to reset you audio system settings when you reconnect the power. Disconnect the battery to protect both you and your vehicle during the installation.
Choose the locations of the lights by marking the underside of the car with the marker. Position the lights along each side of the vehicle. Find locations where the lights will mount directly to the vehicle chassis and will not be visible. Many municipalities have ordinances and laws against neon lights on vehicles, so make sure that you live in an area where they are permitted. Test fit the light tubes in the chosen locations to ensure that they are not close to brake lines, fuel lines, exhaust lines or electrical wires. The location should also not be near moving parts or in areas that become hot when the car is operating.
Attach the mounting brackets to the light tube and hold it up to the underside of the car. Using a marker, mark the location of the screws for the bracket. Center punch each location to help the drill start the hole easier.
Drill each mounting hole and then place a little silicone sealer on each hole before inserting the screws. The sealer will guard against rust forming. Screw the light tube in place. Make sure that the side tubes mount with the wires pointing to the front of the car.
Select a location to mount the transformer. The preferred locations are either under the hood in the engine compartment near the battery, or inside the car under the dash. If you live in a location that has extremely cold weather you should select the interior of the vehicle for the mounting location. Before drilling the mounting holes for the transformer, investigate the region to ensure there is nothing that you will damage when drilling.
Connect the transformer to the lighting circuit according to the manufacturer’s instructions. If this requires you to splice connections together follow these guidelines:
Strip the insulation back 1/4 inch on each wire you will be joining.
Slip a length of shrink wrap tubing over the end of the wire on one side of the connection.
Solder the two exposed wire together using the solder gun and solder.
Add a small amount of silicone sealer to the connection you just soldered.
Slip the shrink wrap tubing over the connection and use a heat gun to shrink it in place forming a water-tight seal.
Connect the power wire of the transformer directly to one side of a switch on the dashboard that will turn the lights on. Attach a wire from the other side of the switch through the firewall using a grommet to make a water-tight seal. Attach the wire directly to the positive side of the battery placing an in-line fuse along the wire within 18 inches of the battery. Attach the negative or ground wire to the chassis to complete the power circuit. When you activate the dashboard switch, the battery connects to the transformer and the lights should turn on.
Go back and firmly tighten all the mounting screws on the lights. Your new neon lights should now work.
