For those of us that also have a Rav 4EV, this LED replacement works great for the plate lights. and are cheap too!! Only .2 watts vs 5 watts for each of the original incandescents

Thanks Lloyd, I just installed a pair of those in my S85 and it is a big improvement. Easy to do but would be really easy with a properly sized Phillips ("star" to Canadians ;-) screwdriver with a foot long shaft.
Very curious that Tesla used incandescent bulbs over the license plate. LED is the way to go.
