Question about lighting ( need good electrical help )

post #1 of 3
Thread Starter 
Alright, so this is more of an electrical question than a computer question, but i figured you guys could help.


So here is the deal, I have a motorcycle that i'm wanting to wire up a small 6" LED light strip to the tail section to work with the regular bulb brake light.

The idea is to wire the LED with the brake light, so that when I push the brake, the regular bulb and the led strip will light up. ( basically a safety light as anyone who rides knows its hard for cars to judge your speed and can quite easily run into the rear of a bike. I live in a big city with heavy traffic, so its a very good chance it could happen to me.

They make kits for this kind of thing, but they are kinda expensive, and I love making things myself.

Cars/Motorcycles work on a 12v system. And was thinking. that basically, I could run to Frys, grab a $5 led strip, and basically wire the strip with the inverter in a series with the regular brake bulb, and that It would work?

It makes sense in my head, but i've never been one to wrap my mind around voltages ohms and all that stuff.
Do you guys think it will work?

Inverter? LEDs don't need an inverter (which produces AC current). LEDs will run happily on DC. It is more likely a bridge rectifier and power filter to make sure the LEDs are getting filtered DC current.

You may end up with a slightly dimmer tail lamp as you're drawing some of the current off of it, but it should work. Try it out by stuffing a bit of wire into the bulb socket and setting up the LED strip.

My recommendation, and I used to ride too, would be to get a bulb replacement that is LED and has a strobe effect when powered on. When you hit your brakes, you get a few short strobes, then the light comes on and stays on.
