Why would flashers come on but not flash

[chiz]

Hey all... does anyone know the answer to this.. I HAVE CHANGED THE ELECTRONIC FLASHERS BUT THE SAME THING HAPPENS. The LED flasher lights are very small but this should not matter? Infact they look pretty dim when they come on hmmmm. Maybe poor ground?Any suggestions would be great.
Thanks Chiz

Just a WAG here: LED's are polarity dependent. Very fussy critters when reversed.

Chiz,

Try replacing the LEDs with the correct (original) stock bulbs.  If they work normally then, those LEDs are not the correct electrical load to make the flasher unit operate.  The bulb seller may have a fix to make their stuff work as you expect.

Not all LEDs are equal. And the packaging does not help. The lack of a STANDARD allows LEDs to be sold like any other light bulb but may not provide the same amount of light. Without getting to explainy it helps to know what LEDs and configuration are in a given light bulb. I think lights should be packaged with a Lumen value or a way of comparing it. Some products are sold this way but not all. I have had my issues with sourcing LEDs and just had to have a short rant....  

Edit to Pat's comment: An LED will not light up if the polarity is reversed. So a dim light is simply a dim LED. An LED is much like a tiny version of a fluorescent bulb. Energy traveling through gas without a filament.

Thing is when one LED was hooked up across batt it was quite bright... White black wires coming out of LED is this significant? or is it just to keep one straight when hooking up.
Packaging was no help....minimum voltage ETC........will check for voltage at light when switch is on my guess is the voltage will be LOW. Chiz

The above is very true. After having purchased various types of LED bulbs. My go to choice is now Cree LED's. These are not tiny bulbs, but look more like little square chips. They put out a tremendous amount of light. All four of my turn signals are Cree LED lights along with my Auxiliary driving lights.

When shopping for LED bulbs always look at which SMDs the bulb uses and how many it has. This will give you a better idea how bright the bulb will actually be. The pictures and chart on this page will help: http://www.saving-star.com/smd-led-comparison/
