It just all depends on the circuitry. Even the kits offered for the aftermarket 05 - 09 may not work the way you intend because you would be wiring a sequencing circuit in externally when there is already one installed in your car. I am more than guessing that the circuitry for the OEM sequencers is not in the taillight harnesses and is elsewhere in the vehicle.[/quote]

10- have led

That is only one difference. You can install aftermarket LED taillights on an 05-09 and use the sequencer kits that are offered as long as you wire resistors and diodes in the correct spots. It could be that the sequencing circuits for the 2010+ are in the taillights, in the SJB, or else where in a separate module. I highly doubt its in the taillight wiring harness.

Why would someone want their brake lights to sequence when you put the brake on? It looks absolutely stupid. The reason the other companies designed them to sequence the brake lights is because it takes much less electronics to design a circuit to independently sequence each of the brake lights. It's all about cost to build and profit margin. Most of the harnesses and such I have seen are made with cheap components that are susceptible to failure after repeated use. Ones that are designed correctly use a microprocessor and tie the two banks together so that when the brakes are applied they come on solid and not sequence. Why do you think Ford designed it that way for the OEM application?

And just so you know what set of lights I am talking about here is the ebay page. Looks like he has a few for sale.

I guess when you are an electrical engineer you look for these sorts of things. I am saying all aftermarket sequencers are shoddy. But I have yet to see one that performs as well as the ones on my car though. :smoke:
I bought the above mentioned kit specifically because they do not sequence a cycle when the brake pedal is pushed. The only time they sequence is when the turn signal is actuated (just like OEM on later models). I didn't want to run afoul of the law, and if I ever got rearended, I didn't want the culprit to claim that my 'brake lights were confusing'.

ok, ummm.... wow. Lots of thoughts on this.... Thanks!

What I want is, when I hit my brakes, the lights sequence out ONE TIME and stay on till I let off the brake. Some may think it looks stupid, I think it looks sweet!

Any thoughts on this?

don't listen to the haters. I think it looks good also which is why I put them on my car.

They sequence out once and then all three lights stay on until I let off the gas. and then if I am turning whichever side I am turning too sequences.

I was on thee fence about getting them as well, but then I saw some other car with them (a honda or bmw or something it was dark and so was the car) that had lights that sequenced out when they hit the brakes, a few weeks later I saw it on another mustang and decided to go ahead and spring the $130 or so for them when they had a sale or something (Mustang Sequential Taillights Kit - Plug-in (05-09) at AmericanMuscle.com - Free Shipping!) pretty simple, unplug the old harness, swap the bulbs over and plug in the new harness.

If you like it get them, if anyone else doesn't like it, well it's not their car so who cares what they think.

Has anybody actually attempted to swap the harnesses? I highly doubt it will work. The factory circuitry also isn't set up to drive incandescent bulbs on the 2010+ cars. LEDs pull hardly any current but incandescents pull a ton. I don't think you want to blow up your SJB do you?

Agreed. Most likely and cost effective spot would be in a logic circuit in the SJB.

Unfortunately, getting a '10+ to sequence once for the brakes would probably be fairly involved on a retrofit basis. I think you would have to have one or more transitor invertors across the two sides to differentiate between a brake event and a turn event. You would also need a limiting trigger circuit so that the brakes only sequence one time. I don't know if the presence of low resistence LED's would add to the difficulty. It's beyond my ability but maybe some young entrepreneur could fill a need in the market.

Anything can be done if you know what you are doing. I just don't want our poor author of this thread to go out buy a harness for an '05-'09 car to find out that it doesn't fit and if he modifies it to fit it isn't going to work; or worse, it blows up something in his SJB (or elsewhere). Without knowing the circuitry in the car I can't be of much help. I was actually in the process of building my own light sequencers for my car on the cheap until I came across the Perfect Flashes on the eBay link I posted. I bought the splice in kit for $89 and it would have cost me about $50 to build a similar circuit. For $40 it wasn't worth my time.

The Perfect flash circuit differentiates between a turn event and a brake event because the two light sequencers are tied together. When both lights come on at the same time the processor knows its brake time and to just turn them on solid.

If the turn signal and brake light wires are separate, as long as you can prevent it from back feeding it would be easy, since once you hook the brake lights up to the turn signal and use the turn signal it will back feed to the other side.

Sorry to confuse, I didn't mean that was the part he needed, that's the one I used on my car and I posted it as reference. He would obviously need to find one for his model year.

I was however agreeing that the brakes lights sequencing out once and then all three staying on as they sequence outward looks good.

I totally agree with you.. There is nothing more ugly then sequencing brake lights and I would never purchanse any aftermarket sequencing kits for this very reason. I will get the one on ebay you linked tho. Thanks

I have seen fire engines, ambulances, police cars and tow trucks with sequential lighting and there drivers all agree that the sequential lights draw your attention to your vehicle, which when you are stopping is the best way is the best way to avoid accidents.

you are right. It will get the attention of a cop.. I know 2 guys who got tickets for sequencing brake lights. Its not supposed to do this(as it was in the 60's) and it looks childish.. yuk

just for the the heck of the high amount of incorrect info in this thread i will say this bit, i have had the cdc seq. sense 07,not one problem, and recently i got LED bulb for them also(no resistors) and guess what, they look better than ever and still work perfect. as far as legalities go,not one ticket.if that were true every old t-bird from the 60s would have been illegal, hell i see city busses with them!

agreed, I see people in here swearing up and down how illegal they are.

however not one of them has provided any evidence to back that up.

And if they were illegal, that cop I braked in front of would have probably got me for having illegal tail lights instead of letting me go with a warning about being a bad driver. (thanks dude wherever you are)
