Has anyone installed a flashing 3rd light? Cost, source for parts, do you like the results?

Got mine on Ebay. I really can't say much on whether I like the results or not since I can't see it when braking.
Look at this on eBay http://www.ebay.com/itm/233220797074

Do I have to replace the bulb? Does it need to be a led?

Is your high mount brake light not led? The original on my 1st gen 2004 was led.

But to answer your question....yes, has to be led.

I have a 3rd brake flasher.

I like the blinker, not sure about folks behind me.

It definately gets attention... also I have superbright leds in it.
