LED Tail/Brake Light?

[Whoops]

So I just installed the Vizi-Tech Supabrake 3 and it seems to be working great so far. The bummer with having an incandescent brake light bulb though is it is much slower to cycle when flashing.

I understand that there are issues with the turn signal/running lights when swapping to LED, but would it be possible to just upgrade the brake and tail lights so I can increase the pulse intensity on the Vizi-Tech relay?

Has anyone swapped those out and if so, what did you replace it with?

Without having to attempt posting a picture, do you have a part number or website link for the bulb perhaps? I have done a fair amount of searching using the Honda part number with LED and haven't found squat outside of a traditional bulb.

I ordered the service manual which I am hoping will state a generic bulb number I can get just about anywhere which might help me locate a generic LED substitute. So no worries if you don't have a part or link.

Whoops, is it the tail light you’re after? The 2013 Service Manual says it’s 12V — 5/21W. I suspect the 2014 is the same.

5/21W is a universal tail/brake light bulb used the world over. Just buy any LED bulb being sold as an automotive tail/brake light bulb. Before you do though you might take the existing standard bulb out and check the two bayonet pin locations. Some manufacturs use differing offset bayonets.

For example, check out this bulb here. You need to look for something like this but matching the bayonet locations that you have on your existing bulb.

OK, will give that a try. I thought there was a standard bulb designation, perhaps something like "3049" or the like. I will pull the bulb and go to an auto parts store and see what models match, then see what I can find online that is an LED replacement.

Thanks!

I think you're right. From the different parts schematics at various parts houses on the web, the 2013 and 2014's seem to be the same bulb and wattage.

Here's what i use at the moment, works fine but the difference between running and brake light is a bit less than i would have liked, still ok though and should last a fair bit and the light output is fine;

Things to watch out for is the dual contacts in the base and the wattage.
Designations are bay15 s ( single contact 15 mm socket ) and bay15d ( Double contact ).

I think bay stands for Bajonet socket Automotive And i give up on the y bit, could be a size unit for the socket.

You want the bay15D variety like in this picture.



just got some spares for the future too.

Here is a link that says it is an 1157 and shows an LED replacement: http://cb1100forum.com/forum/showthread.php?tid=3348

There are most likely more if you search around.
