LED turn signal help

[Roland Gama]

Looking forward to building led turn signals for my Yamaha bulldog.
Each enclosure would house 3 orange and 2 blue XR C leds alternatively flashing at 1/2 of a second.
Help in designing the timing electronics would be much appreciated.
I have a LM555 with a conventional relay in mind but dont know if that would work.

That's not a turn signal, it's a disco light or something. Turn signals emit amber light (except in America where amber or red is permitted at the rear) and they flash at 90 flashes per minute, plus or minus 30. Putting nonstandard lights on your bike may seem to you like a good idea to attract attention, but it's not. There's a very good reason why the function and color of vehicle lights is standardized and controlled: it's so their message is clearly, immediately, and unambiguously transmitted to other drivers who often have only a fraction of a second to acquire the message you're trying to send them. Make them slow down their reaction and go "Hey, wait, what's that...is it a cop, or???", and you run the very real risk of causing a crash.

Thanks for the well intentioned preaching chief!!!
How about this? http://www.customled.com/products/flushmount/flushmount.htm

Let us stick to the basic help requested- the flasher design.
Someone?

This is a good place to start. I live in the states and the last time I had blue lights visible from the front I got a ticket for impersonating an emergency vehicle.Just because you can buy something... imvho

Thanks for the link Chris.

This is what I've done for some extra brake lights I added. From what I remember I had one red/orange in the center on always and four R/O that flashed with this when the brake was activated.

You're welcome. It's good advice, you should follow it.

How about not? You found a toy that you think looks like fun. You don't seriously think the existence of such a toy means it's okay or safe or legal or a good idea to use on the street...do you?

Let us stick to the basic help requested- the flasher design.

If you ask for help doing something ill-advised, you're likely to get at least one response saying so. If not here, then by the side of the road from a cop who's not amused that you're using blue lights without being his or her colleague on the police force.
