How about this one for $20 and super small size - 36 flash functions?

There are some videos of this in operation at this site.

 

I have the BackOff module and am very happy with it.

Buddy of mine has this unit set-up in strobe mode and it's quite impressive.

Jousley........ Yes, Signal Dynamics, who makes the "BACKOFF XP" modulator is what you're looking for. The unit has 2 modes you can pick from. The MODE 2 flashes 5 times rapidly then STAYS ON until you release either the brake lever or the foot brake. I provided links and a You Tube link describing what this modulator does........

Signal Dynamics also makes other forms of brake flashers as well but I think you're looking for the BackOff XP set to MODE 2.
If you click on the site below, you can see how fast they flash and get more info about it.

If you are running L.E.D.'s or might switch to them in the future, you MUST MAKE SURE you order the BACKOFF "XP"...... not the BACKOFF or BACKOFF "MD" or BACKOFF WIG-WAG modulator.

 

Street Glider....... According to that site, their unit is strictly limited for use on a 3rd brake light.....not your primary like the BackOff XP.

 

thanks lwos... i'll return the other and get that

It can be used on any light LED or incandescent. It specifically lists motorcycles. I think its a better deal since you get 36 modes and its real small in comparison.

I'm going to pick a couple of them up in a month or so, and I'll report back.

 

Street Glide.....The BackOff XP is very small as well......the size of half a credit card, and a little thicker. I see your module is very small, and it sounds fine, but I'm only interested in having 1 mode, which is rapid flashing a few times, then automatically going into a steady on unless I release the brake and re-apply, which then the sequence would repeat. Once it's spliced into my electrical system, that's it for me. I dont intend to change or modify it.
Your link specifically states, and I too this from their site.....
" 3rd Brake light flasher allows creating brake flashing effect from third brake light to catch the attention of drivers behind. The flasher module is a microprocessor based circuit specifically designed for third brake light operations and packaged in a very tiny package so it can fit behind any third brake light assembly. It works on both LED and incandescent bulbs (4amps max). "

So I dont know why they keep referring to "the 3rd brake light".

Let us know how that module works out for you. Just out of curiousity, why are you going to pick up a "few more"? Do you have other bikes or are you putting them on autos or an ATV?

"jousley"......let us know how the BACKOFF XP works out for you. I really like mine set up to MODE 2, and as I said in another post, I had a separate switch mounted on my handlebar, next to the master cylinder side so I can engage it as an emergency flasher if necessary. I figured as long as the mechanic was under my seat splicing things, he might as well hook it up to this optional mode.
Now I can have my rear turn signals flashing plus I can push my button and have my brake light flash as well.

 

LWOS - they have to market them for 3rd brake lights on cages as that's the only legal flashing light on a vehicle. I'm sure it'll work fine on 2 wheels, so I'm curious to hear the feedback from SG'r...

 

Basesman1........
see, that's why God created Men. So they can understand these things better. I tend to take things "literally". I know Baggers like Ultras have quite a few rear brake lights mounted from their hard luggage carriers to to tail lamps and all parts in between.
Anyway, it makes sense how you put it. Anytime I can learn something new, I consider it a plus. Thanks.

 

Look at these.....

Look around they also have a modulator and tail/turn combo link up...all same unit....good prices.
In fact there is an Ebay store that sells directly from them too.
