2020 SR5 LED head light bulb???

As for other options, installing H9 bulbs is a great way to nearly double output while maintaining factory projection. Keep in mind that these are a high-beam bulb and will burn out quicker (plan on changing them every 1-2 years instead of 3-5 like stock). You can do the same with the high beams, a 9011 can replace the 9005 bulbs. I have run this setup for a year (both sets are Philips bulbs) and it works fantastically for not much money.

The upcoming OEM LED lights should work great, if the Tacoma lights are any indicator. And most properly designed LED emitters and control systems have insanely long lifespans, so they should last the life of the truck with no need for pricey replacements.

Good move. Despite what anybody (or any company) tries to tell you, installing those aftermarket LED bulbs into halogen housings is a bad idea. Not because they're dimmer- in fact, they can be many times brighter, especially compared to the factory halogens. The problem is that they will not focus correctly, which is what you need in order to see far down the road. This has to do with how your factory headlights are designed to work: they use the tiny halogen filament as a focal point for projecting light into the distance. LED chips, no matter how bright they are, can't yet exist in this small focal point (they need some thickness between the emitters to provide the power circuit and a copper heatsink to mount to).

So when someone says "Oh yeah my LED bulbs are totally brighter" they're not wrong, but they're almost certainly driving less safely at night. They now have a huge splash of light 30 feet in front of their truck, which looks impressive. But now they've overexposed and constricted their pupils due to the extra brightness, and they've lost their distance projection due to lack of focus (what some call the ability to "throw" light). All of this leads to terrible headlight performance, and drastically reduces the driver's ability to anticipate and react to the road ahead (especially at freeway speed).

You don't have to take my word for it, there is a master thread of information by a resident lighting engineer at Tacomaworld here:
https://www.tacomaworld.com/threads/3rd-gen-hid-vs-led-vs-halogen-h11-projector-headlights.589465/

As well as an article interviewing a lighting expert here, including discussion about why people will try to convince you their eyes somehow operate differently than every other human's, and that's why LED bulbs work for them:

This writeup is the exact information I was looking for. It's a summary of the information in one spot. Thanks Tory!

Toyota OEM High Performance Fog Lights.

Upgraded halogens plus the OEM LED fogs works quite well.

Do you know the part number by chance? Also, are these just the lenses and not including housing? Trying to figure out if they would fit my '14 Limited

Well now that there are new DOT regulations (likely due to money hungry lawyers), it is much more difficult to find LED bulbs for headlights.

When they were still "legal" I bought these:
Low beam:

High beam:

About 8 months too late for easy purchase, sadly.

^^^ This... I personally have these and LOVE them!
