Try putting regular bulbs back in. Maybe the LEDs don't draw enough power to make the flasher work.

Essayez de mettre les ampoules ordinaires en arrière po Peut-être les voyants ne tire pas assez de puissance pour faire fonctionner le clignotant.

Not sure what Edgar said, but if you are using LED bulbs you will need an electronic flasher, a regular flasher won't work on them.

Electronic flasher needs to be designed and rated for LED use.

Normal flasher uses the current draw to heat up the internal switch and make it click over, LED's don't draw enough. They use very little current (good,) but flashers are current activated.

The LED bulb supplier should be offering resisters to wire into the circuit, providing enough load to force the normal flashers to warm up and "blink." A special low load electronic flasher will also do the same, it monitors current draw at much lower levels and decides by time interval to work, not load.

The unhappy fact of LED bulb replacement is the circuit has to be loaded back with enough current use to make them work. In terms of reducing electrical power, it's not quite a major improvement - you gain by having the (hopefully) brighter output and longer lasting light that won't burn out.

The final result is that conversion isn't quite what might be anticipated, LED's don't just plug in and work yet. The makers aren't offering "plug and play" bulbs.

Sorry my French is inadequate.
