If anyone else still has any working ones of these installed this might be of use. I bought several sets of these on the cheap to mess around with a while back I fully realize they'll only work against old guns and not modern stuff. Well I have one set installed in the rear of one car. I modified all these to plug in with cigarette lighters so anyway after going to the bank I get back in the car to and seem to smell something electrical. The cigarette lighter plug and lighted kill switch for that set of Blinders is warm to the touch. So I pull the plug checked everything else, and sure enough something is wrong in the rear. I get home inspect the system for shorts in the wiring I used and such. I then get a camera and check the Blinders. Sure enough that set of M-06hps had leaked water and water was behind the lens. I removed that set took them in the house and proceeded to take them apart. While both had leaked water apparently the one the inside glue that holds the LEDs in place had seperated allowing the water to leak underneath and create the short. I dried them both out and tested them with an external power supply and both work again with no apparent overdraw of current. Apparently the extra heat from running caused the water to leak underneath the glue used inside.
The thing is water would not leak in at all if you sealed the rear vent holes. I can't imagine that even running constantly that they'd generate enough heat for that tiny vent hole to be an issue.
If anyone actually still has running sets I'd seal the rear holes with some silicone. This set should be salvageable. Don't even know why I'm wasting my time, however it was interesting to know. This probably would have been a fairly easy problem to remedy from the get go and I wonder why Blinder did not investigate this more closely.
