    I stand corrected. Though a better test in this situation would be one H11 LED and one H9 so we can see the delta. We assume the H9 would fully clear the lens but it'd be great to confirm that experimentally.

    That's rather impressive buildup indeed.

    I don't have pics on hand, but I have seen pics where halogens on a 3rd Gen have cleared the area immediately in front of the projector maintaining output while the rest of the headlight was covered in snow.

    LOL. I’ll finish the high beam testing tonight, full review post will likely be the following day though.

    hey @crashnburn80 , when we turn on headlights, highbeams, and the rest, who powers them? Is it the battery or the alternator? Does the battery provide any power to the lights too?
    I know alternator has varying rpms depending upon the load, so is there a minimum Amps the alternator always put out when the lights are ON?

    I forgot. You're right. Lets assume the case of motor is ON.

    Then it is the alternator. The battery is basically just to get it all started.

    Do the varying RPM of the result in variation in the lights intensity? For example, I know Alternators have a Hot Idle RPM and then there's a MAX RPM. At Max RPM the tow package Alternator puts out 130Amps I believe.

    They should not change the light intensity as that would not be safe in low RPM situations like driving slow

    This is an awesome thread. The OP(s) are incredibly informative. How about a simple list of 'these are what I think are the best/easiest replacements'? Maybe a table?

    After I get through the 12th review with pix etc - i still don't have a simple answer to 'what is the simplest most reasonably priced way to get better output?'.

    I'm not being snide because I fully appreciate the scientific approach. This is how it should be done!

    But, it would be really helpful to have a way to pick some lights.

    I'm not thrilled with my lights and would be happy to replace them - but this is too much data to parse in order to come to a conclusion.

    THanks for the great work!

    ^^ Philips H9 w bulb base mod to fit H11 low beam location. That is the cliff notes answer.

    seems like offering the truck with the OEM LEDs in cold regions would be a liability risk for toyota, wouldnt it?

    Crashnburn80,

    Any chance you’ll test the halogen H11 Sylvania SilverStar Ultra? I know you don’t like them but a comparison would be interesting.

    They are easy for most people to get at an auto parts store.

    I like the results of mine compared to the stock halogens in a 2020 TRD OR. The forward throw and side throw is significant. And they are white enough to look “modern.”

    :)

    this has happened twice now this week but Amazon shipped me 9006 instead of h9. I've called in to Amazon both times so they can double check their stock. I'm ordering ANOTHER set tonight and see if they can get it right on the third try.

    Halogen light output will vary some with voltage intensity, the voltage does fluctuate while driving depending on battery charge and load. It is typically highest right after startup to replenish the battery charge that was used to start the engine. You can see my alternator charge + AGM battery thread here which has my plotted alternator output readings over time:
    https://www.tacomaworld.com/threads/the-northstar-agm-battery-voltage-booster-upgrade.604478/

    I don't plan on it, but if someone wants to send/lend me a set I'll add them.
