Changing over to LED indicator bulbs can be a challenge for some cars.
Bulb/Globe out warning systems can be present on brakes, reverse and indicator bulbs.
These rely on seeing a preset load passing through the connection.
In most cases it’s 21w at 12vDC.
For indicators – in traditional flasher cans (those things that make the indicators flash) they need to have that 21w passing through the connection to open and close the contacts.
So there needs to be something that either goes around that requirement for a 21w load (Electronic Flasher Cans) or something else that artificially creates a load to make that can open (Resistors).
Universal 3 pin Electronic Flasher Cans such as ours can be troublesome to fit at times with their wiring so get back to us we have had some experience with the different types.
