if you go with the plasma glow one, make sure you order it with the optional plug in resistor. when i ordered mine and plugged it and turned on the directional, it would blink the whole bar. called up plasma glow and they basically told me i fried the bar because i didnt have the resistor. i sent the bar back, and they sent me a new one with resistor adapter free of charge.
but, mine lasted a year. and after a year it crapped out. and as far as i know, theres only a year warranty i think. mines been sitting in the garage for at leasst 3 years. the sealant on the one end got eaten away and water got in the bar and fried again. at that point i said screw it. the winter environment i live in was hell on it, and the fact i used my truck for work, landscape debris in and out the truck all the time and all kinds of stuff didnt help either. just my two cents
