    Their H4 bulbs If you have fog lights that take H4 lamps you've got something going on some old Cibe or hella of many years ago. So there's always that most fog lights don't take anything near an H4 they don't have high beams generally fog lights etc so I think just the wording is wrong in the ad which I could care less about these are H4 bulbs they call them fog lights I don't care if they called them poop lights makes no difference that's the Chinese for you that's how they do things they're not fog lights there H4 bezel lamps made to go in H4 housings which generally aren't fog lights but okay this is what I have in three of my generation twos the other one is HID with the D4S to LED conversions plugged in with nothing else done oh well I don't know what to tell you those are quite bright and if you crank your adjusters down and get your cut off on the wall set right You should be in good shape if your lenses aren't completely fogged they work very well I'm quite happy without having to oven bake everything apart install merimoto mini projectors and all that nonsense but hey.

    Installed new LEDs – without removing any panels – and, though difficult and requiring much dexterity and some time, managed to do it. However, the beam pattern appears odd – slanting from top right to bottom left.

    Maybe the bulb is not seated correctly. Off-axis maybe?

    Receipt your bulb in the wire clips make sure it's in their proper it's H4 tab goes up to the top and the other two at what four and 5:00 or something like that and then after you get all that done you need to crank down righty tighty on your adjuster about eight half turns That's what you do with the screwdriver when you turn it once you make a half turn because that's what your hand does then you'll see the cutoff line magically appear on your garage wall now you set that line at whatever height you've been reading about sheets running done.

    The tab position seems correct – two at bottom and one at top I believe. It was the only way the bulbs fit in. Here's the beam pattern below. Another Prius group on Facebook suggested they're designed this way to mitigate the beams shining into drivers on the opposite side.

    I can adjust the passenger side height fine, but how to get to the driver's side adjuster? It's blocked by a top cover piece and seems necessary to remove. Those plastic screw fasteners are damaged easily.

    Noticing the high beams aren't substantially brighter but, otherwise, the overall light appears improved. Of course the light's color temp is modern.

    And, interestingly, bizarrely, the car just sounded an alarm - for the first time ever. We don't have an added alarm package that I'm at all aware of (after 19 years). Driver parked in garage, came inside house, then suddenly – blaring honking, a siren, and all lights flashing. Again, this is a first. And the only thing that's changed is the bulbs. Possibly related. Or what could have started this? Thoughts please...
