Looking for advice on a flashing third brake light mod.
Having fun with my car, as you can tell. It's got a long list of wants, so I figured I'd start working on the next one up now that I've done my shocks.
I'd like my center tail light (3rd brake light) to flash when braking.
There are quite a few products that do this... some are clearly intended for low power applications and littered all over ebay claiming things that they don't deliver. (My favorite is the 1 amp load product that some sellers advertise as capable of 100W instead of 10-15W... good times.)
Now, knowing incandescents and loads, it seems to me that it would actually be easier to go to LED bulbs instead of incandescents, and then blink those: because LEDs have almost instant on/off, allowing a much higher rate of blinking if so desired; because LEDs don't mind being blinked, whereas normal bulbs will die quicker because of it; and of course because switching less power means a smaller, simpler, cheaper circuit.
Since I really don't feel like designing a blinker when they exist for $1 to $50 already at varying levels of quality, I figure I'll take the easy way out.
However! Here's why I'm making this post: I can't find any articles online that talk about LED conversions for the 3rd brake light. Tons of people convert the standard tail lights to LEDs, or euro spec, or whatever. Fine. But if people do convert the 3rd light to LEDs, they don't post write-ups of it. Bulbs they used, whether they had to install special circuitry (like a hyperflash), etc.
So with all that said, question for the forum:
1. Can you simply plug and play 194-compatible LEDs into the 'high mounted stop lamp' (GM parlance) and have it work properly, both electrically, and in terms of light pattern? I don't want to blind anyone behind me.
2. Does anyone have preferred brake light modulators / blinkers? I quite like the designs from http://www.3rdbrakeflasher.com/.
Would appreciate links to past threads if I have missed them. Thanks!

Hey Dude! The center mounted brake light is LED! Just get a flasher, install it and go on to something else! But to quote Bill Curlee "I can't afford to buy anything too cheap"! Buy a good one when you do.
Good Luck!

Look into products for motorcycles. I have one on my Harley that flashes the brakelight, and it has several patterns. It's easy to wire into a circuit. I have it on a setting that flashes about 8 times when triggered, and then stays solid.

Radioflyer Innovations has a 3rd brake light flasher unit that is a true plug and play. George is an excellent CF Supporting Vendor

How'd I miss that Radioflyer has this? Thanks. I'm not sold on the flash pattern though...
Sterling, I'm not entirely sure that the 3rd light is already LED. The GM parts bin seems to say that it's a standard bulb, as the replacement for it is a standard bulb... as near as I can tell...

Buy and install the plug-n-play flasher. I've had one for years.
Note: a nice feature on my unit is that after one brake application (unit flashes normally), if you apply the brakes again within 15 sec (~), it does NOT flash. Prevents constant flashing in creep-n-crawl traffic.

The city buses around here have used a flashing 3rd brake light for years now. After a few seconds, all show a solid red. I have never found anything in WA state vehicle laws that says a flashing 3rd brake light is prohibited.

put a cheap one on my Impala and it worked fine , put the same one on my C5 and it threw codes for traction control and I think ECBM . Took it off and codes went away .

OK. Think I'll try it and see how I do with NJ inspection in the fall.
Now here's another question: If the stock 3rd (5th?) brake light is LED, is there any advantage to the aftermarket ones being sold? I know some are black and some are clear so if you're going for that "look" sure, but what about the red ones? I think this thread just saved me some money!

Is there another way?

It's even easier when you get a flasher unit that has the appropriate plugs, no splicing needed.
I used this one:

There are many flasher units from multiple manufacturers available.
