I did an LED headlight conversion using quality (expensive) units on my 2014 Ford Transit Connect and I'm just not overwhelmed - I was expecting much better
The reflectors in the lenses of modern cars have a fixed focal point, engineered for the placement of the very thin halogen filaments in the specified OEM halogen lamps. As you can see in the above photos, the LED light source is a pretty good sized rectangle, actually two or more depending on the brand, spaced apart by some distance and the focus of my LED's is not nearly as sharp as it was with the halogen filaments. Plenty of light, but much of it isn't focused where you need it to be - It's scattered all over the place. I don't know for sure that any of it is actually coming from the exact focal point of the lenses in the headlights like it was with my OEM headlights
We've all seen hundreds of cars coming at us at night with the blue/white lights which nearly blind us as oncoming drivers and sadly, I'm afraid my Ford is just one more of them. The light is whiter and bluer and all the kids think it looks cool, but I doubt they can actually see any better, and for sure the rest of us can't either when they're aiming those things at us
Never considered LED's for any of our iMiEV's because we don't drive them at night all that often - In 8+ years, we've still not burned out a single bulb in any of the cars . . . . plus, the OEM Halogen headlights in the cars are EXCELLENT . . . . better than any car I've ever owned
