Home Made Emergency Warning Light

This was made with off the shelf Dome and Brake lights that can be purchased at Walmart or similar stores, and uses a 537 relay flasher. The total cost was about $15 to build. Currently I use two Federal Signal Dashmiser dual-strobes, but this was what I had prior to getting the strobes.

what is the housing made out of?

@ptfirefighter I made it out of scrap wood. I never did use the light. Really had no use for it at 99.9% of the time I don't use my lights. But it was pretty neat.

@kd4hvz you have any plans of selling it? would make a nice novelty item

[kd4hvz]

@AdmiralKakarot Nah. It was more of just a project I was tinkering with since I had some time and miscellaneous parts laying around. I could never make enough on it to justify my time. Feel free to copy the idea and sell them yourself if you have any interest. :-)

this would make a good rear deck light

it's a very good idea, I made the same "home made light" with relays and it's fantastic because it is very cheap, you just need to find good lamps and for example it is a perfect solution inside the car, on both sides

@heatherandpaul2 Perhaps you haven't heard of the "fire lane"

Nice

@urbex2007 The flasher and relays are one in the same. It only has three connections; supply, and the two lights. So a DPDT is not needed. Simply a SPST to drop the power to the flasher. The flasher does it all for a measly $5 or so.

It's an indicator flasher unit wired to a relay. As simple as that, so it switches between one light and the other.  The on/off of the relay is controlled by the flasher unit and the lights positive wire to either side of the relay, the common connection being +12v. To stop one light staying on when the flasher isn't on, you need a DPDT switch to supply +12v to the relay and the flasher. Easier than it sounds.
