    No, you want the control of a projector to cut out the glare cause by using the wrong light source (LED) in a halogen housing. Reflectors won’t eliminate the glare and will be hazardous to oncoming drivers. LEDs don’t actually work in either housing, but at least with projectors you are not blinding others on the road.

    You can see a more in-depth explanation on why LEDs in a projector don’t project correctly and cause loss of distance projection among other issues here:

    Excellent thread Crash! Always enjoy following your research in this category. I took your advise on an easy upgrade for Halogens for the low beams. Bought the GE Megalight Ultra H11s. Love them. For the price, an excellent upgrade from OEM. Brighter and clearer with the appropriate cutoffs for my fellow motorists.

    Just to confirm again what OP said...

    Purchased the Spyder aftermarket headlights (also found on Tacomabeast) which look awesome but suck for light output. I had upgraded with Phillips halogens which helped some but decided to take a chance on the LED bulbs which in some ways did increase the light output BUT lost the focused center beam found in the halogen WITH lots of scatter. I found the high beam LED's to be more useful than low beam LED's which did not improve the light output.

    I purchased the GTR CSP mini LED H7 bulbs on headlightrevolution.com for $250 (this includes 4 bulbs for low and high beams). This is a high quality LED bulb and figured I would give it a go...

    Driver side has LED bulb, passenger halogen bulb

    Furthermore, the bulb housing needed slight modification with Dremel to slightly enlarge the opening which was very easy with this Dremel bit.

    IMG_0282.jpg

    The LED barely fit and was a tight squeeze with regards to screwing the water tight plastic cover back on but it does fit with some patience.

    Lastly, as noted in the beginning, the center beam was diminished with LED's. There is a screw in the LED bulb that can be loosened to rotate the bulb to adjust the lighting pattern. It took some trial and error but there was some improvement. The pic below was the first pic I took comparing the halogen to LED. The LED light pattern DID IMPROVE some with rotating the LED lights (pic not shown unfortunately since it was late at night and got tired of re-adjusting, etc).

    I bought 3 sets of AUXITO H11-LED-HeadlightBulbs and couldn't be happier. They are finless so no extra noise, my truck makes enough noise. The LED's work excellent in the projectors, the brights I do expect to scatter but its the brights... I'll take all the light I can get scattered or not for brights. The fogs were a real surprise, they light up great and only in the first 5 -8 feet, I have not had any drivers flash me. The install was simple, the brights only needed to be inserted at an angle starting at the 6 O'clock position then they just slide in.
    Plug & play

    Do you get decent distance projection on the highway with low beams?

    This is low beams and I think they are exactly like the original's but just white, you can clearly see the cutoff and as you can see it is just getting dark and does great when it's completely dark.leds.jpg


    and this is with the fogs

    This has convinced me to completely ditch my HAKARI ultras for some super high end halogens. If your dead set on LEDS, the hakari ultra is the best option on the market for plug and play performance on the 3rd gen taco. BUT, everything in the OP is true and I experienced it first hand. They were "brighter" but not "better". The Hakari has an INFINITELY better beam pattern than the LED used in this test and it still gets its ass handed to it by a good halogen in beam focus, and most importantly distance. I lost a lot of cast distance for a "gain" in brightness up close and a change in color which is subjectively better or worse. The Leds are actually noisy too, as the Hakaris are so powerful they REQUIRE the fans on their fins. Ive touched them while on parked and damn do they get stupid hot. Not the LEDs themselves, I mean the heat sink. So I can only imagine the LED itself is hotter than the surface of the sun. You can hear the fans running quite loud from inside the cabin with the engine off. I can definitively say I got scammed by the LED hype on this one. I even gave them the best chance possible by not buying the cheapo option.
