Indicators . help .

They look like they're LED's
which mean's you need resistors! (if you haven't already blown them)

Shouldn't they at least flash faster?

not necessarily. they need to draw a certain threshold current to get the flasher to run...

you need to connect a 6.8 or 7.5 ohm 20w (or 2x10w, or one if you aren't worried about the heat) in parallel on each indicator. it will cost about $12

You should still get a flash, even without the resistors.
Check your polarity and switch them, if that doesnt work they are dead.[hr]
Can also get Resistors from Jaycar Electronics, very cheap for components.

these will help

i prefer these,

theres no flash at all , and i dont think it's blown cause when i put it directly to the battery it works ..

have you got them connected the right way around?
being a diode, they will only let current flow in one direction.

This happened to me.

I bought and connected ONE set of resistors/relays and the indicators turned ON and STAYED ON.

So I went back to bought another set and connected the second set too. And it worked.

Just FYI.

leds are polarity critical and will only work 1 way unlike incandescent where u can hook the negative to the positive and it will still illuminate.
