Can you tell us more about this upgrade? Very cool idea, I am interested!
You've not heard of a headlight relay upgrade? The gist of it is that you take the OEM wiring out of the equation when providing power to the actual bulbs (higher resistance, larger voltage drop). Draw power directly off the battery, through a relay that's switched by the OEM harness, and to the bulbs via the shortest runs possible with larger gauge wiring. It's a simple system, I like to DIY for the cleanest install, but even a plug-n-play aftermarket harness will offer improvement.
That, in and of itself, will brighten headlights because they'll get more voltage. Running hotter bulbs is questionable with a plastic housing though, I've personally melted a few with 80w low beams. Amazing upgrade when you have real metal and glass housings though.
For the OP, I've been looking into this too. Generally speaking, I've not seen anyone who's an actual professional within the lighting industry recommend bulbs swaps. A housing is designed for a specific type of bulb, the way it provides light. There are no HID or LED bulbs that Exactly emulate a halogen, so the reflectors throw the light out poorly. Yes, there is "more" light in most cases, but is that light where you NEED it, or is it just scattered all over the place.
I know, some people make claims... are they profiting from those claims? And humans are fickle, we don't want to make bad choices so we often Perceive things that we've invested personal time/money into as being worth the investment. I saw this time and time again as a motorcycle dyno operator,
The only viable option I've found for better lighting are projector retrofits. Look hideous, function great, take a fair bit of work to install. I'm seriously on the fence about installing them because of just how BAD they look. Well, there's always adding accessory lighting. I'm considering that option too, 2 sets of smaller projectors in the bumper, a "fog" light that's switched with the lights and a "driving" light that's switched with high beams. Those should address the lions share of lighting issues and look better than a projector retrofit in the headlights.
Beware of the TYC housings if you're going to run halogen bulbs. I've seen complain that they have issues with the inner shield (part that sticks forward inside the housing) being wonky and causing less than optimal light output. Several threads on this forum about that.
