    Don't buy that China crap. If you want a strictly off road only light, just swap in an H9. It will far outperform the GE in output in addition to the above lights while providing a fuller and more uniform and wider angle beam pattern, because it is the exact light source the housing is designed for, just massively brighter and lacking forward facing glare protection. The Hella Osram Hypers are an elite performance +30 version H9 for even greater output performance, and they cost a whopping $9/each. All you have to do is trim an internal tab on the bulb with a small knife and they are plug and play.

    But by using an H9 you lose the glare cap and these will produce forward escaping light creating awful glare. Not actually as bad as LEDs in halogen housings, but bad glare none-the-less making the mod not suitable for street use. This should be an off road only mod. Lacking the glare cap also eliminates the cut offs, meaning the fog function of having hard cut offs for poor weather performance is lost.

    $30 for pair (not a problem) but looking at other sources for the Hella Osram Hypers and not finding "hyper" in any Hella H9 bulbs except on rally lights.


    are these the same bulb or Mexican crap? also is the Volsa H9 a good capped option vs the Hella un-capped h9s

    The Hella standard H9s are the Hypers, but Hella has 2 different versions of the H9 bulb. Those made in Korea by Osram and those made in China. In the 3rd gen Headlight thread post 339 someone ordered the double pack off Amazon and confirmed they are made in Korea though I haven’t tested the bulbs to be certain they are the same, but it does seem like it:

    https://www.tacomaworld.com/threads...ector-headlights.589465/page-17#post-19886349

    The capped Volsas are not available. But the Hellas will be higher output. Neither option is very street friendly as the TRD fogs don’t do a good job of glare control so even a capped H9 in the TRD housing will magnify the poor glare control.

    Left bulb is stock, right bulb is trimmed. Note the metal tabs have 90 degree corners vs 45s.

    Is it not necessary to trim the metal tab as well?

    Only some H9s require that, I don’t think the Hellas do. I’ll double check.

    Hella H9s fit without meta tab trimming, but it is a tight fit.

    Is it possible that the cutoff line (on a wall, for example) would be slightly higher with the GE Megalights, as compared to the stock bulbs?

    I can't say for certain, but I kinda think the line is higher on my garage wall than it was with the OEM bulbs at the same distance. Is this even possible? Or is it my imagination?

    Bulbs can have small variances in focal points for how a smaller filament high efficiency bulb focuses compared to a standard larger filament bulb. Usually this doesn’t require much if any adjustment and is more fine tuning optimization than anything else. Of course this assumes you had quality European made bulbs to begin with, and not cheap Chinese ones where the filament location may be significantly off which would alter the pattern position.

    Shoot. Ha I meant to post that in the headlight thread- not this fog thread. Too many crash tabs open on the desktop!

    Actually makes more sense in a headlight than a fog light. :)

    I look at this thread every so often just to see how things are proceeding. I've run the H9's in my outfit for about three years now - and they are without a doubt superior in light output to the factory H-11's. They really do the job on dark rural roads and I didn't have to upgrade the wiring. But...................the comments I've seen about the "glare cap" requirement troubles me.

    When I fitted the bulbs, I parked the truck squarely in front of my favorite warehouse wall (level parking surface / vertical wall). I first fitted the passenger side bulb - and then checked the wall for the "cut-off" compared to the factory arrangement. As far as I could see - the lense worked to limit the brighter bulb to exactly the same cut--off elevation. If that is the case - what would be the added effect of the glare cap - the cut-off is the cut-off correct?

    I think this is the case for the low beams in the (3rd gen anyway) but not the case when putting into the fogs.

    Other bulbs
    GE H11 Megalight +130 is by far the best performing stock wattage H11 bulb I have tested. See this post. They even outperform H9s in the 3rd gen headlight assembly. I still need to test these in the fog assembly, they may replace Volsa H9s as the recommended bulb.

    I'm often asked for bulb recommendations for "whiter" high power bulbs. I recommend non-coated bulbs, but for those looking for a whiter bulb there is Optilux 80w H11. Not Recommended. See my experience with Optilux.

    Yellow bulbs: Optilux makes a glare caped yellow H9. H9 is an extremely high performance bulb, I have better faith in a stock wattage high performance bulb than a high wattage one, but I have not tried these myself.
    Optilux 65w yellow H9

    Nokya also makes a 75w H11 3100k 'stage 2' bulb.

    I didn't think you could get the Optilux 65W H9 yellow with a glare cap. Ive been looking for something like this, still cannot seem to find them.
