Yeah So i've been running my DDM's for about 6 months or so now, no issues...just pulled up and noticed on the garage door that only 1 was on...I fiddled with the wires alittle to see if there was a short, nothing....I'm just guessing the bulb is blown. I had no warning signs like flickering or flashing etc...just bam, OUT! ... I am running a wiring harness also sooo...suggestions anyone? is there an easy tell-tell way to see if the ballast is gone vs the bulb?
thanks...
