I own 2. Both are solid blue. I have one in my Expedition and one in my Canyon. I wont use anything else for primary warning. On my Canyon, it is the only forward light I have. No HLF or grille. I have zero problems moving traffic in the day or night. I get excellent interesction coverage at the critical angles. I never have problems with any "dark-time" since it is always on. When one section is covering the interstection, the other side is providing the forward warning. I will be adding the MP-13s in a pair shortly to the grille. With the flashers in blue and the sweeps in white. I will add a pair to the rear with one in blue sweep/amber flash and amber sweep/blue flash.
I actually was following a state trooper to a call one afternoon. After all was said and done, he came back to my expedition. He asked me where my lightbar flew off at. I had a really dumb look on my face i'm sure. I told him I didnt have one. He swore up and down that it was me behind him and that I had one. I had to turn everything back on and show him the light. I had the DL-12 with shield dash mounted, 2 lx4 in grille and a HLF. He said to turn off all but the DL. He walked in front of my truck to look, walked back to his car and looked, and then got in it and looked in his rearview. He got back out and wanted to know where he could buy one. Said it had the appearence of a full lightbar. He was 1/2 mile ahead when we were responding and parked about 100 yards infront upon blocking.
I've had several guys try and buy them off of me. No way. I am about an hour drive from their facility. I speak to the president on occasion. Excellent guy to deal with and really knows his products. I am really looking forward to anything new they come out with in the future. I would even put a VOLT on my canyon if I could.
Now alot of guys gripe about it being an led with a motor. And how it defeats the purpose of led... Nah. Its a concept that the "BIG 3" didn't try first so it automatically is a bad idea in alot of doubters eyes. Whatever! I get tired of hearing that crap. I also hear about the amps and how putting it in motion takes us a step back to halogens and rotors. The DL draws nothing close to an C3 or FS rotor with a 55 watt bulb. If it is such a bad idea, then why did I see it on a V-bar at FDIC this year?
Ok... enough rant... My opinion is, get one J... I do not believe you will be disappointed. If you are, contact me and I will buy it off of you myself. I believe in its quality as a primary warning device that much.
