I vote for HIDX lights myself!
And, just a correction... the Rugged Ridge lights are NOT the same lights as ours. HIDX and our parent company (who designed, built and owns part of the plant who manufactures them) are the only 2 brands that will ever be sold to the US of this actual light. There are a few companies, RR included, that COPIED our lights and are manufacturing them in a different plant in China (presumably). While I cannot say they are good, bad or indifferent... they are not the SAME lights.
There have been over 40,000 of our lights sold into the US in about 2.5 years. Our lights have run the Baja 100, King of the Hammers and many other hardcore races. In fact Loren Healy won KOH with our lights. He actually had a very well known brand of halogens on his rig also, that both broke. GenRight also finished 14 and were sponsored by us in KOH. I think a total of 16 race rigs ran our lights in KOH. The bottom line is that our lights are proven successful over time, and in harsh conditions. NONE of the other "inexpensive" HID companies can say that about their lights.
Halogen vs HID... HID are 35 watts, draw barely over 3 amps each and are roughly 3 times the intensity with a more comfortable and appealing "color" of light. They also do not have filaments that can break in harsh conditions. So... better durability by design, better performance in output, and much less demanding on the electrical/charging system of your vehicle. All of these advantages, for only a little more money when compared to the "top of the line" halogen lights.
Let me know if I can answer any questions for you, and good luck with your decision.
