room in rear lens for slightly larger brake/tail bulb?

[RickJ]

I want to put a flashing (3 rapid flashes then steady) LED bulb in...it looks like the OEM bulb is 1 1/2" long (from end to end) (http://www.partzilla.com/parts/detai...6-MBB-611.html) the replacement is 2 1/4" long (https://www.superbrightleds.com/more...Specifications)

I like to avoid removing the lens 2X...once to measure...put it back...order...take it off... So I'm just wondering if anyone remembers offhand how much room there is under the lens...I used this (bayonet type though) in another bike and it is plug and play and feels a lot safer...

I know about the other alternative under the license...but this with the new Kury light below would be my preference for now (for now! HA famous last words)

Anyone?

Humm I'll be watching this as that is what I'd like to do also.

Well I just took a looks and I say you have that extra 3/4". I shined a bright flashlight in there and the bulb looks recessed from the rear lense fairly good. And there probably is a buffer as you would not like a warm incandescent too close to the plastic to heat it and deform it over time. I will be watching this as well.

Lots of detailed pics here. Maybe ask a question of the seller for a quick measurement?

As I understand it this LED is a duel function LED, it is a running light hen when the brake is applied it goes super bright with a three flash blink and we would need two of them as there are two 7443 duel function run/brake light bulbs in the F6B?
Another ? as we all know most lighting systems require an LED compatible Flasher or Load Resistor(My Rune has a LED flasher). LED brake/tail lamps may not flash with most stock flasher units, is this going to be an issue too?

This appears to be an internal electronically controlled LED lamp system Apply 12V and the on board electronics tells the LED to flash then go solid. Having a load resistor installed in turn signal flashing circuit typically is required for a self cancelling system or a mechanical relay which cannot sense enough current draw from an LED to engage the relay contact correctly. Then you have the flashing at 3 or 4 times the normal rate.

A braking/tail light system will have a singular ground and two voltage inputs. One is on all the time for the running/tail lamp filament, then a second voltage input when brakes are applied that will cause a second filament to illuminate.

Here is the 7443 dual filament bulb.

I say it will be plug and play.

Using a bulb like that will not shin the best I have tried ones like that looks bright and night shinning on the ground but it doesn't use the reflecter so it looks really small at the lense

My Triumph is a 2004 Thunderbird Sport...Hinkley made.: I've had 0 issues with JUST changing that rear bulbs (there are 2 in the trumpet too) I don't expect issues.

To take a slightly different tack on your question, I might ask, what is it you are trying to accomplish?

If you want the bike to have flashing LED brake lights, there's another, maybe better, way to do this:

Step 1: Buy new LED bulbs and flasher from SoCal Motosports or some other vendor.

Step 2: Buy an inexpensive wig-wag module off Amazon. I found one called SHO-2011 for under $20. It's compact enough to fit on the rear lightbar.

Step 3: Buy a TIR-3 or comparable strobe light to mount in place of your rear reflector. There is a flush-mount version that's a lot easier to install.

With these components installed, you will have up to 12 different synchronized flash patterns...meaning the brake lights and TIR-3 strobe all flash in unison.

You can even go one step further and install a push button switch above the license plate to change the flash pattern...

This solution provides significantly brighter brake lights by upgrading to LED bulbs, added conspicuity of the TIR-3, and still more conspicuity from the wig-wag flasher.
