I was also looking for that. For some reason Toyota left Halogen there, despite every other light is Led on the Car. Looks like there are two options, one is to just replace the small halogen T168 bulb with Led equivalent, or replace with whole thing along with lens assy with 3rd party light. Second option is brighter, but expensive, and little more work.

The 2nd video you linked shows how the “Harrier” one I linked will work on our Venza, thanks. I’m at work now so can’t look into it but the panel he used with the ring of lights should fit ours. Now I can’t wait till I get home 😂

 

This past weekend I replaced the puddle light on the bottom side of the side mirrors with LEDs following the disassembly procedure in the following video. Supper simple and much brighter.
Puddle Light LED conversion The actual instructions begin at 2:15. One thing he did not mention in the video, if the bulb does not work, pull the bulb out of the socket, rotate it and put it back in so your switching the polarity. Maybe I've been lucky or the bulbs I used the polarity does not matter because they all worked the first time putting them in.

These are the actual bulbs I used since I had a few left over from another vehicle iBrightstar Newest Extremely Bright Wedge T10 168 194 LED Bulb You can even choose a different color if you wish.

 

Thanks for sharing good news. Any photos you can share to give us some motivation!!
Also, some reviews about the powerful leds says these melted the plastic as those are becoming too hot. May be we shouldn't put too powerful leds?
