Default Led Expert need here

I'm troubling with led bulbs 95 vette.

4 red led bulbs tailights in, and all other bulbs are incandescent car properly works.

If even two amber front bulbs led are in, car blinker still works if parking lights are off.

If i turn on light then blinker stuck on

Already tried tridon el32 electromechanical and cf12anl flasher led. Both same thing: blinker stuck on

I'm searching around, find out this..they explain something...but is notsolving my trouble...

http://www.ebay.com/gds/LED-Turn-Sig...6783681/g.html

I would not install resistor...if would be possible

It is also possible that cf12anl is not the right one for my car.

A guy here reccomended me to use ef32...

Where are you buying your LED? In Italy or USA and shipped to you?

Provide a part# off of the invoice that you've got that mentions part# specifically. Post the actual invoice if you can maybe!!

All LED #'s for what you're using for external lighting!

1157 bulb size 2835 chip 15 SMD amber --- It is for the front park light/turn signal has 15 led

1157 bulb size 2835 chip 27 SMD red --- it is for the four rear tail/stop/turn has 27 led

The strange thing it is that cf12anl has no minimum load required, so should works, instead it is not working


Would this one be better?

As matter of fact i've not invoice or part number.. This is the only things i've have about bulbs...

I've made some other test today...
Wagner 323, 552, cf12anl01, el32, all these flasher won't go...

Amber led bulbs are not responsible, since i've put them in tailight and properly works

The only case that entire system properly works both with lights on or off is the hazard... This case blinker works...

The story is definetly getting weirder...would be curios what hazard flasher i've in?

Seems to be a load trouble according with the owner manual. In fact AFAIR, if an incandescent bulb is blow out then Blinker stuck on manual says

NO - the component in the wiring schematic is this:

http://www.ebay.com/itm/1995974-1991...-/322056577234

It's just the first image I came to that will validate/answer your question.

I believe what you've got in the snapshot is the cruise control cut-off relay. Is it right next to the flasher left of column? look at 8A-201-24
