Check My Work
 

This is the setup I plan to use for my fog light. Let me know if this just plain won't work as I expect it to and why or if this can be simplified while retaining all functions I have designed. This should cause toggle or brake to result in solid fog. Reverse to result in flashing fog. Reverse with either toggle or brake on flashing. Thanks for the help guys.

Sample Parts:

3 Pin Electronic LED Flasher: Virtual Village - US
Bosch Style 5 Pin 30 - 40 Amp Relay W/ Resistor

You think you don't know anything, well my head must be in a paper bag then.

Question:

What is the purpose of a Diode?

Why a resistor as well as the flasher? I understand the flasher...

Are the pictures of the brake, toggle and reverse the lines that go into the tail lamp assembly.

All I was trying to do was to have the fog lamp blink 3 or 4 times when I brake then go to a solid RED until I let my foot off the brake pedal. The addtional blinking while reversing would be nice but not essential.

This is a good thread for most of us :)

i agree, and priced accordingly

A diode keeps the current from bleeding back to the other side. Otherwise activating the toggle switch turn on the brake and reverse lights. There is no resistor, it is a 5 pin relay. This allows the setup to default to a solid non blinking form until reverse is activated. At that point the current from the reverse lights throws the switch inside the relay directing the current toward the flash. The results is that by default the toggle switch and brake lights activate a solid light while reverse throws the switch resulting in a blinking light.

Flashingbrakelights.com has a nice module which will blink six times and then stay solid upon braking. If this is all you need you can purchase from them. In addition to what they have I am also wanting to add external control for a solid fog and blinking in reverse, not just six times but until I am no longer in reverse.

I just learned something.

Thank you. :tiphat:

holy **** CBRich..is there ne way we can get a DIY for thiis set up for the noobs?

Body Control Module (BCM)
 

At this point I'm not even sure my setup would work as I'm just learning about this stuff as I go. But I plan to order the necessary parts and try it out.

A couple points about your parts list and plans:

1) You're linking to a Zener Diode, which is probably not want you want. You probably want a regular old diode. Zener diodes are designed to allow reverse current flow when the voltage potential exceeds a certain preset, in the case of the one you linked, 12V :).

2) That 3-pin flasher module you've linked sounds like its intended to flash at the same rate as typical turn-signal flashes, which is significantly slower than what an F1 rear blinker would flash like.

Thanks wstar. If you look I edited my post with the correct diode soon after posting it but it had already been quoted. Do you see any issues with the new diode?

Also, I was just looking for a standard blink rate but if you have a link to one with a bit quicker flash I wouldn't mind checking it out. Thanks for the feedback.

Edit: Possible Flasher

Oops, guess I was looking at the quoted copy :)

Yeah that diode looks good, assuming 1A is enough current. You might double-check the current draw of the flasher + the LED tail-light to make sure that 1A continuous is plenty for the both of them. I have a feeling with how bright the LEDs people use in car lights are, it might be an issue. If it is, just pick another diode in the same series with a higher current rating.

I may be using the standard bulb that comes with the light which is not LED. In that case would a no load flasher still work fine? I'll have to check the draw of the standard light also to see what it looks like.

Just did some calculations on the bulb that comes with the lamp. It is 21W at 12V so 1.75A is what that comes out to. So using a 3A diode should be sufficient. Such as this:

Don't forget you're driving the flasher from the diodes as well, so add the flasher's current draw too. And don't ask me anything about automotive bulb flasher modules, I have no clue :)

Is there any kits out now where it keeps the stock black look, but keeps flashes red when I am braking & backing out?
