LED bulbs
 

I just put all LED bulbs all the way around (rear, mirrors and front). Now the hazzards work and blink, but when I try to put an individual blinker on either the left or right, i get a high pitched buzz from under the dash and the front and rears stay solid and the mirror lights don't even come on....any ideas...thanx in advance.

i do not know if the L's came with an electronic flasher, if they didn't then that could well be your problem.

did a quick search and came up with this

Do you have any pictures. I'd be interested. Where did you get the bulbs? Thanks.

I bought them off of ebay and will post a picture when i get it all up and running...i messed with it a little this morning, and if i keep the front blinkers regular bulbs ,they work, the blinkers blink fast, but work. Thanks for the thread search too. i did that last night but all this resistor talk and what not, I don't have time to invest in some light bulbs to start messing with resistors and all that nonsense...I'm not that electrically inclined anyway....I just need the quick easy fix.

Don't think that there is a quick fix. The LEDs draw a fraction of the current of a bulb. So the electronics are confused, thinking that a bulb is out.

Splicing in some resistors may be the only way out. It's a shame that these bulbs are not offered in a resistor and non-resistor model (like spark plugs).

there was a company that was doing something similar to that(this was a few years back). it was hz engineering or something. dammit i forget the name now.I might have the addy saved on a cd round here somewhere.

because i am that damn good


Hz Engineering

I saw on e-bay some led tail lights/brake lights, that go around and around in a circle all the time the truck is running. And when you put the brake on they get bright and they go around in circles. I thought it might be neat, but again it might be a little much.

Still no joy -- they are the same non-resistor types that he has now.

"Q: Why do my turn signals not flash at all when I install LED
bulbs?
A: This is a common problem on most older vehicles. The
origional reason why your blinkers do not flash is to allert you
that you have burnt out signal bulb. The reason that they do not
flash when LED bulbs are installed is that LED's are very energy
efficent. They use so little current that the signal circuit see's
them as a burnt out bulb.

Q: How do I correct the fast flashing problem?
A: You will need to purchase, and wire in one of our LED Load
kits.

Q: How do I correct the non flashing problem?
A: You can purchase one of our wire in LED Load kits or you can
go to your local auto parts store and purchase an "electronic"
flasher module (not a heavy duty flasher)."

They can put a man on the moon . . .

yup. close as your gonna get.

Actually, there is a quick fix, I bought these for mine, and they work great:

The Lightning flasher/deadbulb-detect circuitry is of course, very sensitive to the resistance of the lamps. (thats how it tells a bulb is out). If you put in one LED without a resistor, you'll "fast flash", if you put in two (like you did), you won't blink at all until you splice these puppies on to each LED that does not have an built-in resistor.

Besides the Hz place above (which disappeared for a while) and through many dollars expense and trial and error, I have found that the two best LED light makers for our truck are these guys, the top, while expensive has the best peripheral side-lightning that our rear and front blinkers need. The second, is just pretty cool. :)

I custom made 40 led taillights for my truck.... that stuff is weaksauce :p

I'll take some pics and post them tommorow :)

ttt, pics?
