Car Black Lights

You can hack the blacklight above by splicing the wires and connecting multiple blacklights in parallel and then mounting them in your car where they are needed. You are going to have to be creative when figuring out how to mount them, but once you do the inside of your car will look amazing!

NOTE: Disconnect battery
Be sure to disconnect the battery when doing any electrical work. This will save you from burning out any fuses or other important electrical components.

Here is a step by step guide to installing your blacklights using the type listed above. You are going to need 4 to 6 of these blacklights to get good coverage of the whole interior.

These are the things that you will absolutely need to complete this project.

1. Blacklights
2. Electrical switch
3. Extra electrical wiring
4. Wire cutters/Splicers
5. Sandpaper

And other supplies needed based on how you decide to mount your blacklights.

Overhead:
Its best to first figure out where you will put your blacklights. I found that putting them on the edge of the roof is the best and easiest way to go. You can hold them in place with a small metal plate or some other way that looks cleaner. Four of them mounted overhead above each door/seat will give you good coverage. The picture on the right shows how I did it.

You should figure out where to mount the blacklights before you do any wiring so that you can plan exactly where the wires will go and how long they would have to be.

Underdash:
You can also mount your blacklights under the dash, one on each passenger and driver side, so that they will illuminate your legs. Again you will have to be creative and figure out how to best mount them according to your vehicle. I used duct tape here to secure the blacklight with a metal support behind the glovebox.

Switch placement:
Place your switch somewhere convenient where you can reach it while driving. Avoid drilling too many holes in your dash panels. I drilled a hole in the panel under the dash so that i could reach it yet its still out of the way.

Once you have mounted all of your blacklights, its time to install all the wiring. The lights should be connected according to the wiring diagram to the right.

NOTE: Sand Contacts
When splicing the wires, make sure to sand the copper a bit with sandpaper to ensure a good electrical contact.

NOTE: Check Polarity
The neon lights must be wired in a specific direction (there is a positive and negative wire). If you get the polarity wrong then the lights won't turn on. On the right you can see that each wire is marked according to its polarity. The negative wire has long gray boxes on it and should be connected to ground. The positive wire has little writing on it and should be connected to positive. Be sure to test which one is which just to make sure.

Battery Connection:
Connect a wire to the positive battery terminal clip. Find a hole in the firewall that leads to the inside of your vehicle. You can run the wire through the firewall so that it comes out under the dash. Connect this wire to your switch.

Hiding the wires:
Try to run the wires from the blacklights under the plastic paneling and under the dash or under the carpet to where your switch is.

Connecting to Ground:
Find a screw or a bolt under the dash that screws into the frame of the car. This will be your Ground. You can connect all of your negative wires to it.
