What if I said the key factor here was the fact that the lightbar works at night/morning (when I go to work) but not during the day? It appears as if my lightbar has a case of vampiritis. But seriously, that is the biggest thing I noticed but blew off as thinking it was a power supply issue.

“A Xenon flash tube can be very photo sensitive. One will flash normally when exposed to an external light source, but may become very hard to fire when subject to darkness.”

Lets just flip that around. It makes perfect sense. This ties in with another thing I’ve noticed, one of the corner strobes has blackened but still seemed to fire normally at times.

Thus far I have disconnected the one corner strobe. Firing up the strobes in takedown mode, the front and rear strobes fired up. The corner strobes did not, which I kind of semi half quasi expected. But the front and rear strobes appear to be reliable during the daylight hours.

Could I have finally found the problem? Time will tell as usual.

UPDATE 0100: As of midnight, the lightbar was in complete strobe failure. I’m going to disconnect the remaining corner strobes today.

UPDATE 1430: Disconnected the remaining corner strobes, the front and rear strobes appeared to function. Lets see if this lasts through the night.
