Hey everyone i was hoping someone can help me here. I want to mae something that will allow me to flash my tail lights sequentially for the blinkers, and then for the brakes have them flash out and stay steady,i have 3 lamps to light in order example. blinker: 1-2-3 reset 1-2-3... Brakes: 1-12-123-steady.
I have general electronics knowledge and i assume something could be made using a 555 timer, any help would be GREAT. i would assume the one circuit for the brake light would work because the blinker goes on-off-on-off which would start the circuit then turn it off, start, off, but idk. something more smooth would be better but that might work
so basically i need what one person in this old thread was going to create but never did

I installed a kit similar to this one in our 05 Mustang. Works great!

just be aware unless your car is one of the old 60's T-birds OEM equipped with them (or model year 63 or earlier I think), they are completely illegal and a citation waiting to happen

oh sincethe federal government made them illegal... late 60's.
Go read FMVSS 108 and it will give the date it was changed.

Well someone better tell Ford about the law, since they are using sequential turn signals on the 2010 Mustang.

That was revised in 2004. Have you read it since then? Nothing in there prohibits sequential turn signals as long as they don't " impair the effectiveness of lighting equipment required by this standard".

no i havent read it since then. not a ricer so i don't have to worry about lighting violations

to clarify, I haven't read the turn signal bit since I looked at sequentials some time between 2003 and 2006. they're still illegal btw.
where is a recent change to make them legal???? in- phase is still in the language, and they are still using 588e (1970) and 588 1984. in other words nothing has changed re turn signals or stoplamps since 1984 at best, and or most states that don;t reference fmvss 108 reference 588e directly (1970)
Do YOU have a reference showing a change since 2004 making sequential turn signals legal again? If not they are still illegal. Period. unlessy oulive in a state that doesn;t simply reference fmvs 108 or sae 588e and instead spells out the lighting code... without stating sequentials are prohibited.
you state they are legal. prove it.
ford sold sequentials illegally for 3 years after 588e (70-73), Toyota sold all the 2000+ celicas with illegal headlights. 'it was sold that way' doesn't make it legal.

No one in this thread has to prove anything. YOU made the wild claim. Show everyone line and verse where it states they are not allowed.
BTW- I just asked my nephew (who is a LEO) and he said they are not illegal. He also said that even if they were illegal that no cop would be foolish enough to take the time to give anyone a ticket for one because there is sooo much paperwork involved. In any event, we'll be waiting for your so-called "proof"

Again...
SAE 588e (1970 proves illegality.
requires rear turnsignals flash "in phase" with front signals.
There is no question, there is no dispute, they are illegal.

Well there's the problem... you just don't understand what the phrase "in phase" means :)
BTW - our car will also have front sequential turn signals, so by your own admittance there will be no problem with them :)

Regardless if it is legal or not... if you have enough electronics and soldering experence you might want to try:

I have yet to try it out, but it is on my list of things to do... Im trying to upgrade all my exterior lights to LEDs, and thought that would be a neat effect.
