back up light duel: stock OEM 921 v. Sylvania SilverStar 921 bulbs in 2010 Toyota Camry 1/30/23

This is a comparison of the back up light performance of 2 different incandescent 921 light bulbs installed in a 2010 Toyota Camry: the Sylvania SilverStar 921's are featured first and then the original stock OEM Toyota 921's are featured second. While the Sylvania's seem crisper, in reviewing the footage I realized the vehicle placement was not equal between the 2 bulbs and that diminishes the comparative value, especially of the light output on the driveway. I am going to redo the test again when the weather warms up a bit. While the SilverStars look nicer, I'm not sure they actually put out that much more usable light on the ground in the case of the Camry or if they do, how much more. After watching it again, it appears they do put out more but the positioning of the car might be affecting that.  
The date is 1/30/23 and we are in suburban St. Louis in the city of Manchester in St. Louis County. P.S. 1/6/24. I have finally found, after 2 or even 3 fails, some much, much brighter led backup bulbs for this vehicle, which bulbs actually stay in the socket and don't fall out. I will be posting about that very soon. There are many bright leds out there--keeping them installed and not falling out is the secret to better lighting in the back, and it is way more complicated than just getting brighter bulbs. I actually accidentally screwed up the back up lights of someone close to me because of that issue and just because they look bright doesn't mean they will stay in the socket--long cylinder-style 921's act like a lever and they usually just eventually fall out of the socket because the socket was designed for the much shorter and lighter incandescent OEM bulbs, not the new longer, heavier led's of most manufacturers.
