Here's Why Some LED Headlights Work And Others Just Blind Everybody from buzai232's blog

LED technology has come a long way in the last five years, and in 2020 there are a bunch of brands selling well-made, well-engineered LED replacements for your car’s old halogen headlight bulbs. Here’s how to figure out which ones to get.To get more news about led headlights, you can visit iengniek official website.

(Full Disclosure: Be careful when modifying your car, especially with anything safety-related, like headlights, as not all aftermarket products are going to be road legal. Do your own research and mod at your own risk!)

The appeal of LED headlight “bulbs” is simple: Increased light output for better nighttime visibility. And lower power draw. And! They make an old car look more modern. But if you buy a pair, it’s critical to understand that more LEDs do not equal better light. In fact, the good LED bulb replacements actually have fewer diodes.

(Just to be clear, we’re talking about aftermarket LED retrofits where you swap halogen headlight bulbs for plug-and-play LEDs and don’t mess with the factory headlight housing otherwise.)

TL;DR

If you’re going to use an LED bulb replacement in a standard reflector headlight housing, you want one with the light chips that install in exactly the same position that a halogen bulb’s filament would be.

LED bulbs with a multi-sided barrage of diodes look like they’d provide more light, but all they really do is blind oncoming traffic.

When you buy the right bulb, make sure it’s installed correctly!

Context

For a long time I was staunchly against LED retrofits and I always advised people to just run high-performance halogen bulbs if they wanted the best lighting in older vehicles with stock reflector light housings.

However, technology has improved since I did my first LED-vs-halogen comparison test in 2015 and so has my understanding of light science. For that, I have to shoutout Chris Nelson at Headlight Revolution. That’s an online headlight bulb store that also has an informative YouTube channel illustrating the finer points of modern headlight mods.I don’t know them personally and have no professional affiliation, but wanted to share this new HR video because it does such a great job showcasing why LED bulb replacements bristling with diodes are actually crap. The ones you want use fewer, more tactically placed, diodes.
