Hi to All,
Looking at the Holleys, i had mixed feelings. IMO there are pluses and minuses with them.
PLUSES.
7 inch shallow fit plug and play setup. Semi sealed so you can remove and refit other types of H4 bulbs of your choice. They offer up a powerful light output in energy saving leds. (low watt drain is 25 watt on low beam and 30 watt on high beam. That low watt draw can give you a choice of installing relays or not) Choice of different Kelvins. (warm white, daylight etc) These are sold as bright white 6500 kelvins,but you can buy warm whites at 3000kelvins.
Minuses.
Too expensive cost. Limited life polycarbonate lenses that will cloud over and yellow up in time. Glass lenses are forever in that regard. No option of a Halo led light around the perimeter of the headlight. These bulbs put put 2000 lumens on low beam, and 3000 lumens on high beam. That is equal to 125 watts on low beam, and 200 watts on high beam. In Australia, where i live, these led bulbs are illegal to drive around on public roads. Wherever you live around the world, you would have to check up with your local or State authorities to see if they are permissible or not.
For me, the minuses outweighed the pluses, so i gave the Holleys the slip. What i ended up doing, and i was very happy with the whole end result was, to buy a pair of semi sealed H4 7 inch lights, that came with stock Halogen bulbs, plus an Led white Halo light setup around the perimeters of both lights. I dealt with a great American company called Octane Lighting. They sell this setup as i just described. In my case, i wanted to run Led lights, so i easily swapped the Halogens out for a set of leds. My led bulbs are rated at 1000 lumens on low and 2000 lumens on high beam. (75 watt and 125 watts ) These are a touch over my State regs for watts power, but that is a risk i choose to run with. I run a 6500 Kelin bright white bulb, but you can buy warm whites as well. The halos look great as well. I use them for the front parking lights. The cost of 2 lights was close to $59.90 US. The company makes a big selection of lights, so there a many to choose from. References.
