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

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.

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).

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 . . .

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.
