Momentum V91 -

...."According to the National Highway Safety Administration (2010), most rear-end collisions can be reduced by 90 percent if trailing vehicles had one additional second to react.".....
And I bet if people got off of their "iStupid" phones and video map displays they would have that additional one second that they need to react.

I don't see how those people use their iphones and drive. I mean, where do they set their burger? Kidding... I think when people are looking at their iphones (and android phones, too), they pay WAY more attention than when eating something. I can't tell you how many times I've watched someone start moving about 5-10 car lengths AFTER the car in front of them has gone. But, this is the Momentum V91 thread so I desist... However, that isn't stopping this talk about Momentum V92 which will most likely be trying to convince us that some simple flasher built into the brakes is wonderful news! Does the Elio currently have a third brake light?

..........Does the Elio currently have a third brake light?

I was 100% planning on installing my own if it doesn't, but coming with one from the factory would be a much better solution to me. Heck, I'd pay extra for a CHMSL-equipped rear hatch if it shows up on the configurator.

It won't be very high... unless you install it on a stalk of some sort!

It could be mounted right where the top of the hatch and roof meet. A small "Aero" third brake light, similar to a "wing'..

I'm wondering how it will work with what Continental is doing.
And isn't the data collection and upload part of what the Skyzmatic (optional) doing?
Here's where I wonder if these two items from alpine are going to be standard or optional?

So... a third brake light for the Elio? Maybe? Perhaps a predictive 3rd Brake light? I suppose that makes sense. Think about all the vehicles out there with advanced safety systems. It's great that your car will stop by itself before hitting something. What about that truck following you? Wouldn't it be a neat safety add-in if your car could turn on the brake lights sooner? A half second earlier would give that truck 44 more feet of stopping before hitting you. (at 60 mph)

Check out vololights.com, they have a motorcycle license plate frame with a deceleration warning light that comes on when you slow down/decelerate.

Put light on the back of the wheel fairings, and light the entire rear of your Elio in LED's and hook that to it.
Done right, it would look like the whole Elio is a brake light.

I did not see it in person, but it looks to me like the E1C has a 3rd brake light ?

1&2 - turn signals, running light, brake lights.
3 - Backup lights red section has no light, reflective only.
3rd brake lights must be mounted higher and separate from other brake lights.

I have a Chevy Astro van light I'm going to use, and mount at the crest line of the roof

The one below is the same light, mounted on a Triumph TR6

And just to be specific about the 3rd brake light:

Centre high mount stop lamp (CHMSL)
In the United States and Canada since 1986, in Australia and New Zealand since 1990, and in Europe and other countries applying UN Regulation 48 since 1998,[79] a central stop (brake) lamp mounted higher than the vehicle's left and right stop lamps and called a "centre high mount stop lamp (CHMSL)", is also required. The CHMSL (pronounced /ˈtʃɪmzəl/)[79] is also sometimes referred to as the "centre brake lamp", the "third brake light", the "eye-level brake lamp", the "safety brake lamp", or the "high-level brake lamp". The CHMSL may produce light by a single central filament bulb, a row or cluster of filament bulbs or LEDs, or a strip of Neon tube.

The CHMSL is intended to provide a warning to drivers whose view of the vehicle's left and right stop lamps is blocked by interceding vehicles. It also provides a redundant stop light signal in the event of a stop lamp malfunction. In North America where rear turn signals are permitted to emit red light, the CHMSL also helps to disambiguate brake lights from rear position lights and turn signal lights.[citation needed]

The CHMSL is generally required to illuminate steadily and not permitted to flash,[80][81] though U.S. regulators granted Mercedes-Benz a temporary, 24-month exemption in January 2006 to the steady-light requirement so as to evaluate whether a flashing CHMSL provides an emergency stop signal that effectively reduces the likelihood of a crash.[82]

On passenger cars, the CHMSL may be placed above the back glass, affixed to the vehicle's interior just inside the back glass, or it may be integrated into the vehicle's deck lid or into a spoiler. Other specialised fitments are sometimes seen; the Jeep Wrangler and Land Rover Freelander have the CHMSL on a stalk fixed to the spare wheel carrier. Trucks, vans and commercial vehicles sometimes have the CHMSL mounted to the trailing edge of the vehicle's roof. The CHMSL is required by regulations worldwide to be centred laterally on the vehicle, though UN Regulation 48 permits lateral offset of up to 15 cm if the vehicle's lateral centre is not coincident with a fixed body panel, but instead separates movable components such as doors.[18] The Renault Master van, for example, uses a laterally offset CHMSL for this reason.[citation needed] The height of the CHMSL is also regulated, in absolute terms and with respect to the mounting height of the vehicle's conventional left and right stop lamps.[83] Depending on the left and right lamps' height, the lower edge of the CHMSL may be just above the left and right lamps' upper edge.

The 1952 Volkswagen Bus was equipped with only one stop lamp, mounted centrally and higher than the left and right rear lamps which did not produce a stop lamp function.[citation needed] The 1968–1971 Ford Thunderbird could be ordered with optional supplemental high-mounted stop and turn signal lights integrated into the left and right interior trim surrounding the backglass.[84][85] The Oldsmobile Toronado from 1971 to 1978, and the Buick Riviera from 1974 to 1976 had similar dual high-mounted supplemental stop/turn lights as standard equipment; these were located on the outside of the vehicle below the bottom of the backglass.[84][86] This type of configuration was not widely adopted at the time. Auto and lamp manufacturers in Germany experimented with dual high-mount supplemental stop lamps in the early 1980s,[79] but this effort, too, failed to gain wide popular or regulatory support.

Effective with the 1986 model year, the United States National Highway Traffic Safety Administration and Transport Canada mandated that all new passenger cars come equipped with a CHMSL. The requirement was extended to light trucks and vans for the 1994 model year. Early studies involving taxicabs and other fleet vehicles found that a third, high-level stop lamp reduced rear-end collisions by about 50%. Once the novelty effect wore off as most vehicles on the road came to be equipped with the central third stop lamp, the crash-avoidance benefit declined. However, it did not decline to zero, and a CHMSL is so inexpensive to incorporate into a vehicle that it is a cost-effective collision avoidance feature even at the long-term enduring crash-reduction benefit of 4.3%.[87]
