indicator speed challenges
Steve Lovelock - 29/4/08 at 09:15 PM

My indicators are quite fast and I am not sure what to do about it.

I am running LED rear indicators with a resistor in line as supplied by Europa. I have a side repeator light and a set of front indicators running with 21W bulbs.

Should I consider switching the side repeator bulbs to 21W as well?

Any other suggestions?

You can get a led flasher unit, not expensive, search fleabay.

like this


fixed the same problem for me, ditch the resistors too.

you might like to try ebay item
3 Pin Electronic LED Flasher/Blinker Flash Signal Fix Item number: 250239121302
goes at same speed regardless of load.
(the + and _ blades are the wrong way round for a ford so the wires need swaped)

Definitely ditch the resistors as they are a potential fire hazard.

LED flasher is the proper way to do it but watch the loading - some will only allow 21W ie one filament bulb in circuit.

You could always convert to LED lights all round

Thanks guys. So to get this straight, I ditch the resistor (which cost more than the new relay!) and buy the new LED relay. This will power my LED rear indicators, 5W repeators and 21W front indicators.

Or am I missing something?

That is basically right Steve. I am amazed at how many people still insist on using ballast resistors, when changing the relay is cheaper and consumes less power. The resistor can only be considered as a temporary solution as it is really just an electrical bodge - any light supplier worth his salt should not recommend them and simply supply the correct flasher unit for the job.

I did it because the light supplier recommended it, a little annoying though.

Light supplier recommended them to me as well. Just as a point of fact though, the resistor dosent fit in series, it fits in parallel. Do that and the flashing issue will be resolved.

That was your mistake. You should have asked the question on here and would have saved a few quid.

It is extremely rare for a question or problem posted on here not to be answered or resolved.

So keep up the good work chaps!!

Carry on.

Will having the resistor in parallel really work?


RazMan - 30/4/08 at 01:01 PM

The purpose of the resistor is to force the LED light to appear to draw the same current as a filament bulb (~2 Amps) which allows the bimetal flasher relay to flash at the required rate. As the LED only draws a fraction of this current, the resistor is connected in parallel to the LED unit and dissipates the extra current in heat. If the resistor is too small, it can overheat, especially if the indicator is left on for any length of time (ie hazards) which is why it is not a good idea.

The correct flasher unit does not depend on such high loading and the flash rate is generated electronically, consuming very little power.

How have you wired up the resistor??
Bet Europa didn't tell you.

Attatch one end of the resistor to one tail from the light, then the other end goes to the other tail.


edited to say your not looking for the above answer!!! ooops!
