Lightbulb Led brightness

i had bought some led's for my tails and reverse. The reverase i love cant complain. I have a small problem. when i press the brakes the tails get slightly brighter, as do the right and left blinker. i am assuming during the day you probably wont see it blinking i am using the same flasher and plan to change it but i was wondering if there is a fix that someone has come up with?

If you go to ledlight they have online support. I'm not quite understanding your question about brightness...but they can help.

On the flasher part, though, you don't have to get a new flasher, you can use a "load equalizer" which is just a resistor that goes between the + and - of your bulb circuit, all it does is mimic the resistance of the incandecent it replaced.

This is true but it kind of eliminates the very reason for using LEDs - their reduced current draw. An electronic flasher will solve the problem for about $8 and five minutes installation time without adding unnecessary current draw.

That won't work in some cars that require the circuit to be properly loaded.

It will work in any car that uses the standard 2-prong (as all f-bodies do) or 3-prong thermal flasher. Granted, it won't work in newer Mustangs that have a "flasher control module" - but who cares? The idea is that the electronic flasher provides constant flash speed without relying on current flow like thermal flashers do. You lose any indication of a burned out bulb (T/S goes on but won't flash) but that's not a big concern for most people.

so what about the leds? it seems they are at full brightness. and when i press the brakes they only get slightly brighter. just enough to notice a change.

I was speaking in regards to cars other than F-bodies, my CL will not work that way. Also, any circuit on the car that requires loading will not function properly.

To truly function as a brake/tail you need to have a dual circuit LED. Assuming you do, then my speculation is that they are operating as designed. Did you go to the site I sent you?

F bodies have to have a specific draw on the system. An electronic or LED flasher will make the flashing function work, however having had LEDs in all my f bodies it will do one or more things to it. In my 97 it disabled the ABS because the draw is so low the car thinks all the bulbs are burned out. In my 99 it disabled the cruise until I installed the load resistors until I did that the cruise wouldn't work. My 95 was the same way as the 97. No ABS without load resistors.

If your cruise works than you won't need the resistors. Try looking at superbrightleds.com. They have pics of all their on/brake on to compare how bright they are. They did last time I bought anyway. Will depend also how many LEDs are in the fixture too, but you already mentioned that. Oh one thing I did is I had to have a set quick and just bought the ones they had at autozone and they work great. Really bright too.

what about a device that turns off and on the blinker light instead brighter and dimmer

Default LEDs

I have 100% Leds. I have 7 watt leds in the whole taillight section. I would conservatively say it as at least twice as bright as stock. All electronic flashers are not the same. I cut 3 apart. I ended up with an adjustable electronic flasher but the adjustable part was to support my sequencials.

One of the above pictures shows the difference between turn and parking lights. the sequential is just starting

Load resistors defeat one of the advantages of LED's.
