Ranger & led sequential lights

Leigh . They only do short flash about 2 led's while the engine is not running & nothing when the engine is running.

Thanks Max video etc , My ranger already has a trailer loom ford adapter for LED trailer lights .
probably just shitty lights

Your adapter will have resistors in it. The car is designed for incandescent globe's of with higher current draw than Led lights. Resistors increase the load to the original current draw.

In the video they are using capacitors. The capacitors hold the current in the circuit long enough for the sequential system to finish.

Rangers basically have computer controlled lights, not a flasher unit like older cars.

Try the lights on 12v off a battery.

Thanks Max , I have connected the indicator straight to a12v battery & it works correctly but doesn't blink of course. I have also connected the flasher wire to the brake and tail lights and they then flash okay so it's the sequential part is the problem ?

What is puzzling me is that it still has the incandescent light current draw from the original lights still connected. So could it be that the ranger indicator system is just not suited to the sequential mechanism of these lights . These are cheap !! not the very expensive types you see .
Appreciate your input.

Edit .. Hmm I may have misinterpreted the use/ benefit of the capacitor I.e after reading carefully what RMD said in his reply

I had a 2016 Ranger.

One trailer one model Narva led, no problem.

Another trailer a different LEd light had hyperflashing, solved with 18W resistors.

Another trailer a different model narva led had hyperflash. I tried many different resistors and still no good. I had to take them off.

The Rangers are just very particular.

Ford supply a resistor adapter fot this problem mine already has one .

If the resistor is fitted correctly the indicator unit and dash tell tale should be operating normally. TO me, if the duration of the running LED DISPLAY is LONGER than the NORMAL ON time of the flasher unit, you may require a small ELECTROLYTIC capacitor which charges with each ON pulse at each input to to the LED UNIT, BUT keeps the RUNNING LEDS going AFTER the flasher unit has turned off and readying for the next power delivery. All split second stuff here though.
