You have to be very careful here. Strictly speaking, most of the LED retrofits are illegal. The issue is that the optics in your headlights are designed to work with the very specific light pattern emitted by the OEM halogen bulb. Most LED retrofits can't mimic this enough to meet specs. The end result is throwing light where it can do harm, like in the eyes of drivers going the opposite direction. Sure, you'll get more light on the road where you want it also, but the problem is light going where you don't want it. That said, some of the LED retrofits are approved for street legal use.My partner swears up and down my headlights are dim beyond rational comprehension. If she's driving my car, the brights are on and she STILL thinks my headlights are dim. I'm used to it, but I do see a lot of cars now with far brighter lights. I've cleaned my lights a couple times like Youtube told me, but I see a lot of conflicting advice or when or if it's OK to replace the ones I have. Amazon seems to want to sell me lights that are anything up to 15x as bright as what my car is supposed to have. If I stick even the most modest LED bulb I can find in my car, they're 4x as bright as what's there now. Shouldn't that rate a talk with a cop or is this just what people do now?
The fact we're talking yellowish light from the halogens, versus white light on a lot of the newer vehicles with LEDs, may affect your partner's perception. All other things being equal, we perceive whiter light of the same intensity as brighter than yellowish light.
