Freakin' Angel Eye Flashin'

[Kryptonite]

OK folks, I need some assistance. I've got aftermarket AE's in my '03 4.4i that were working fine until one day (don't know what happen) my passenger side AE started to flash/pulsate. This is when the remote is activated or when the acc is on/truck is cranked. It will then pulsate with the music; getting bright when a bass note hits and dimming otherwise. After about 10 mins of driving, I can park, shut the truck off, and it will be fine. once I lock the doors (remote is OFF) and unlock the doors (remote switch back ON) it will start to flash again. I've tested power from the battery post in the front, before and after the fuse, after the relay to that AE and to the driver side AE; power appears to be constant with the tester and not fluctuating. Im thinking that the ballast associated with that AE is going out. Im considering buying a set off ebay, splicing out the current ballast and putting in a new one. Any thoughts on this or where my problems are?

Thanks,

Krypto
