View Full Version : How to make super cheap working cop lights.

6th Mar 2013, 11:12 PM
I was bored tonight, so I thought I would make a tutorial on how to make super cheap cop lights. I got this little car for 97 cents at a GoodWill thrift store.



The video above shows you the light pattern that came with this. Later I will remove the circuit from this toy, and wire it in to my lighting bus wire with the correct voltage using resistors to make the lights work like they were in the car running off two AA batteries.

Just for test purposes, I used a plaster paris car I made for less than a penny.


Drill holes through the car with a pen vise, and install fiber optic wire and glue it in place.


Here is a view of the top with the lights in. If your doing this for permanent installation, you could use a better car material so its not chipping away like the plaster.


then I done the headlights the same way.


Unless you have more then two hands, you will need a helper, My wife is mine for tasks like this, and I used an accelerator to make the glue harden instantly.


You can see the lights all installed here. Normally the lights would be under the table and your fiber optic wires would be going through the table, this is why you will need a helper more than normal.


more videos below of finished lights.

Nice Scott! Don't everyone raid your kids toybox or the thrift store...
Plaster or resin car?

How come I can't thank your post?

No idea.. its a plaster paris car. I wanted to save the fiber optic wire. I am thrifty lol.. So after the tutorial I am going to break the car in half to get it back out. I will only do this on resin cars with super detail. This was just for the tutorial.
There won't be a toy with flashing lights in it for miles if this gets out on all the forums.. lol.. ha ha..

I think because it's in the Tutorials forum.

Fantastic work Scott! Years ago I built a 1/200 scale 747-400 with lights in a similar way. I soldered up a chip board for the flashing lights, tucked it into the fuselage, and ran fibers in every direction.... I actually ran wire down the main landing gear (disguised as brake lines) and installed contacts under the wheels, and had the power source built into a diorama base.
