    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:

    Even having seen that earlier when @replica9000 posted it, it is still hilarious to read again!

    I appreciate you taking the time to write this up. Very informative. Going to stick with my halogens. Thank you!

    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.

    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).
