Backing up, I think light to the sides is almost as important as light straight back.

Speaking of insane starting (a guy with a username of budynabuick may know this), Dad's 1953 Buick Super V8 Hardtop with Dynaflow transmission, started by turning the key on in Park and pushing the accelerator hard to the floor. There was a switch under the gas pedal. I've no idea what idiot at GM thought full throttle starts of cold engines was a good thing, but I don't think it lasted long.
None. Auxiliary reversing lamps are permitted. Some Corvettes have them, too, though they're on the rear sides rather than the front sides if I recall correctly.
Actually, I think those Saab lamps you're talking about (and the Corvette items I have in mind) conform to the cornering lamp standards, SAE J852 (front) and J1373 (rear). These have tight control of upward (glare) light. J852 has 500cd max at the horizon, 400 max 1° up, 300 max 2° up, 200 max 3° up, and 125 max from 10° up to 90° up. At 2.5° down, the minimum is 300 or 500 cd depending on horizontal angle. So they want those lamps putting light on the road surface, not up in the air or far away. Mount height is 30 to 76 cm from road surface to optical axis of the lamp. For the rear cornering lamps, the minimum requirement at 2.5°D is 40 or 80 cd depending on horizontal angle, and the limit at horizontal and above is 500 cd. Also, "The rear cornering lamps should be illuminated only when the ignition switch is energized and reverse gear is engaged".
You could meet the intent (and very probably the letter) of the front and rear cornering, i.e., aux reverse lamps, with a fog lamp equipped with a low-wattage bulb. That would practically limit your choice to a fog lamp that takes an H3 bulb, because you can get 35w H3 bulbs, and even 27w H3 bulbs.
Regarding reverse lights, what is the best way to do it if you really need BRIGHT reverse lights for safety, since driving where you can't see is obviously dangerous, but you don't want to cause an unsafe situation when you're just backing out of a parking place in normal, everyday, civilized society?
My solution for a number of years has been to replace the round grommet-mounted lights in the truck's flatbed with old non-halogen PAR36 sealed beams
I'm looking at using these lights (Blazer UW3534) which cast a flat, wide beam, and from my tests, if properly positioned, don't interfere with the tail/stop lights being discernible, but I would like your input as well.
Welcome! It's good to have you here. We welcome most. However, the forum has certain rules that are more restrictive than the laws. This is common practice.I am an engineering litigator. Let us review the legal questions with an objective mature perspective.
The current trend among content hosters is to brace for a coming application of laws in the place of posting, hosting, and viewing. But I am not a lawyer.1. The forum rules actually state: "...you will not post any messages that are ... violative of any laws." That literally means a post violates the forum rules only when the language of the post itself violates a law of the jurisdiction which governs (typically the place of posting and the place of hosting).
The moderator would do well to accept that the forum creator said what they meant and meant what they said -- no more and no less.2. To suggest that the forum rule prohibits a discussion -- of whether something is violative of a law, someplace, somehow -- itself is a blatant violation of the First Amendment to the U.S. Constiotution.
CONCLUSION -- discussion concerning the use of a high power back light, or substitute for a 921 bulb in another application, is valuable and well serves the public interest in lawful use under several of the motor vehicle classes enumerated above. My above identification of a higher power ERC / 1991 compatible bulb, with the W2.1x9.5d base of a 921 bulb, plainly assists a multitude of internet researchers in affecting more efficient solutions to certain transportation or other engineering problems which they may face.

The lawyer didn't notice that the thread is 1-1/2 years old? I wouldn't want him representing me in court.

Toyota Prius, too.I wanted to throw my hat in the ring for this slightly off-topic item regarding applying the brakes when starting the vehicle. The fact is that vehicles equipped with push-button start DO require the brakes to be applied before they will start (at least the three that I have been in ... Nissan Sentra, GMC Terrain and Cadillac XLR).
Besides that, I find it odd that anyone would suggest it's bad form to have the brakes applied when starting any vehicle ... I recall being told to do that during my driver's education training course, before push-button start even existed (seems like an eternity ago now)
There are no regulations anywhere in the world that require a vehicle's brake to be applied before the engine will start, and there are no vehicles built that way. But I doubt foot-on-brake starting is killing the CHMSL bulbs. Their wattage is too low and they're "cushioned" by too much thin wire for there to be much of any surge-kill effect. I suspect poor-quality bulbs are a more likely cause of the early/repeated failures.
I very recently rented a Ford Edge that required you to press the brake pedal before the car would start. It had no ignition "key", just the fob which needed to be in the car and a start button on the dash.
