So I'm sitting there looking at this setup, and I got to thinking to myself- 'Self, why are there red lenses over the traffic lights if they are red LEDs?' The DOT specifications state very clearly that they are to be red LEDs, not clear with a red filter. So WTH?
After a few beers (as most every decent and worthwhile project begins), I go head out in the shop with one of the 12" stoplights. I figure I've gotta figure this out and if it takes sacrificing one of these things, hell with it. So after some quick precision work with a 4" grinder, bingo-
Not just the red filter, but another OPAQUE filter under that one as well! HAH! LIGHT THIEVES!!!!
To my delight, I also discover inside that the 18 Lumiled LEDs are neatly mounted on a board, and the driver is mounted on a separate board, and they are both secured inside the traffic light housing with screws!
SHWEET! Now, to find out if I wrecked it by performing surgery or not- I wire nutted the pigtail to a plug and-
*POOF*
I promply blinded myself by staring square at the damn LEDs when I flicked the switch.
That hurt.
So now they're about twice as bright, and where the footprint was once 12 in diameter, it is now 4 inches square which means MORE LIGHT!!! Not to mention cutting the weight of the light panel WAY down by getting rid of the traffic light housing, which will make it a hell of a lot easier to adjust elevation of the light panel. I've got a couple weeks before I get home, plenty of time to devise a totally new platform on which to mount everything... I'm thinking about an aluminum panel with a pancake fan for cooling... muaaahahahahahaaaaaaaa!
