There are two empty reflectors already in the front bumper. I'd like to use those and the false bumper mounted spotlights as hiding spots for LEDs.
There are TONS of parts and options out there, having trouble sifting through all of them.
Thanks!
Also, be prepared to provide the main battery voltage, and any other power sources on the Jeep. I see one model "requires 4 C and 4 AA batteries (sic)" in addition to having a 12V battery for the traction motor, but your son's may be different.
mtonne, what's your skill level with building things electronic? Can you wire some parts together on a perfboard? Can you solder wires onto an existing board if necessary? zespectre's ideas are pretty good if you are up to the task (though I'd be more inclined to power it from the 12V in the vehicle). Can you program a microcontroller? What do we have to work with?
Another thing to consider is if these are for your son to see while driving the jeep, or for people to see when in front of it? That could be a large difference in brightness, and thus possibly a different design. I assume you are interested in daylight visibility.
If you want to emulate a real police car, you'll want it so bright people can't see anything else in the area ;-)
