After trying out many H7 LEDs bulbs for low beam, none of them worked. The substrate that the LEDs are mounted on are just too thick, putting the light emitting elements out of focus for the projector. The beams were just too dim and unfocused. There are just too many wild claims and false advertising in the market and eBay, a big waste of time and potential hazards.

You need to focus on the LUX measurements, not LUMEN.You dont care how many lumens if the beam cannot be focused to produce high lux on the road. 1 LUX is 1 LUMEN per square meter.

To save you time and money testing bulbs, this is a very comprehensive tables of test data of various brands with pricing



Based on these data, I bought a pair of the latest HIKARI for $32.5. Will see how they do

picked up those Hikari LED bulbs, they light up really nice... Had to JDM the plug and fitment of course, but they work with no jiggle....

Hikara H7 low beam.. 60w, 10,000 Lumens.

I used an old pair or rubber retainers from an old HID set, that was stolen out of my car, for leverage to maintain the bulbs position... The harness to the bulbs are too wide, and I ended up taking apart a separate harness from those eclipse headlight I took off and made a haness that was able to plug directly to the stock harness (Mcguyvering the shit out of them, but they've held up.) Next week it'll be a year since I've had them on...

Hikari
Utra LED Kit

Bought it for $32.50 on eBay.

The Headlightrevolution guy on Youtube pushes GTR ULTRA 2 for $200, not much brighter or better in beam patterns.

Will use your info when I install these bulbs.

H7 LED bulbs are much brighter than Halogen. LEDs with fans in the back is the brightest., but the size and shape of LED bulbs with the fan wont fit properly into the Celica's socket.

Bought a pair of Hikari for $35, allegedly produce 8000 Lumen white light each about 20x brighter than OEM stock. I can line up the tab on the base of the bulb into the slot on the socket and insert it all the way in. The LED elements would be in the exact position as the Halogen filament and the lens would focus the beam. But the black connector adapter cannot be used with the LED's fan in the back. So the clip spring cannot hold the LED bulb in tightly.

With the clip spring loose, the weight of the fan drag the back of the bulb down, moving the LED element away from the optimum focus point, LED beams are therefore odd shaped, not a flat beam that sine a swath of road in front of the car.

I had to use foam to shim the bulb in place, but the foam does not press the bulb's base tight against the socket so the beam is not focused. I will fashLon a rubber ring around the base of the bulb to help the clip spring hold it in tight.

The head lights work OK now, but not a solid swath of light in front of the car. So I am still trying to improve it. Strange thing I put in LEDs in antoher Celica and it worked perfectly. I dont remember exactly how I did it, and I am afraid to take it out as it may not work again.

LEDs are worth it if they focus the beam properly. Will advise progress.

I pondered on these for a bit, before I bought the LED bulbs. Saw them on Amazon and their fitment reviews were 50-50 at best, so I passed on it... If you do get these, let us know how it fits, may reconsider it...

The Hikari KEDs fit perfectly in the H7 sockets, but they could not focus into solid beams regardless how I adjusted the position and orientation of the bulbs. There were also ghost beams pointed up high. So I returned the LEDs for full refund.

A couple years ago I bought a pair of H7 LEDs brand IRONWALLS from China, cheap like $15 a pair. Each has a fan, runs very hot but they are very bright, brighter than Hikari, and could focus into bright, solid beams. They are in my son's Celica. I am afraid of taking it out and screw it up.:


You should try that brand. You will need the adapter to hold the base firmly into the socket to lock the spring clip and focus the beams..
