These are semi Large, heavy build cast material, high quality lens, very attractive units, solid hardware etc. I have them mounted at 10' on the top of my Sprinter. First time I turned them on at night I said to myself ""holly crap"", and quickly turned them off. It was midnight and I live in the city so I'm sure I lit up a few houses. Frankly, I didn't want something so obvious as these flame throwers but again, do you want performance?. I have 2 LP6 Pro Amber and 2 White. These will be used to travel across mountain passes, blizzards, foggy, rainy, icy and dark remote locations and this is the proper solution for the value of the van. Do insure that you purchase the factory harness, as someone said for the price its simple plug and play with factory connections. a no brainier. Only question now is that for $500 lights, I surly expect the company to support them. Time will tell but for now, the product is highly recommended.
