Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Fitting Clear LED Side Repeaters

Hi,
Have just purchased a pair of clear LED side repeaters to fit to my R100 Roadster. Can any body advise if I will need to fit a resistor and if so, what type of resistor and where would I need to fit it.
Thanks in advance.

You shouldn't need to. The main filament indicators at 42 watts each side will provide enough current draw to operate a conventional electro-mechanical flasher relay as normal. If the flashing is provided electronically by the BCU it still shouldn't make any difference given the very low current draw of the LED repeaters.

I had to place one ....otherwise the indicators going to fast

I am afraid stefan s is right. That is the common experience, the LED flashers having more or less the double frequency. At least here there are no MOT problems with that, but it looks a bit odd. That is the reason I did not want LEDs there, have them everywhere else exept the mains (too expensive!) I do not know if there is a LED flasher with a built-in resistor, you might try this company: https://www.bettercarlighting.co.uk/
If you have clear indicator lenses and want a colourless, not amber bulb to avoid the "fried egg look", there are ordinary incandescent amber bulbs with chrome on the outside. They appear colourless when not lit up, amber when lit. It is what I have done, works ok.

As I read it Dave is only changing the side repeaters to LED. These take GLB286 filament bulbs of 1.2 watt each as OE. Changing these to LED will mean minutely less current draw but insignificant compared with that from the two main 21 watt filament bulbs front and rear.

Changing the latter to LED will make a big difference to the current draw and likely flasher speed however.

Ah, yes Richard - you are probably right. So we are both correct, but you are the one answering OP's question.
Cheers!

Dave, I did exactly that but left the main indicator bulbs as std filament ones & as Richard points out, the current draw is so similar everything worked fine

Hi All,
Thanks for the responses. Richard is right. I am only replacing the side repeaters. The main indicators front and back are still filament bulbs. I thought that it should not require a resistor unless I replaced the front and back indicator bulbs with LED’s. Will fit over the holiday period and confirm.
Thanks again.

Hi All,

LED Side repeaters tested this morning and can confirm that Richard is right. The fitting of LED Side repeaters does not require a resistor. I can also confirm that if you put an LED bulb in either the front or back indicator unit it will require a resistor to correct the speed of the flash.

Happy New Year to all.

Thanks

However, if you have a plug in flasher relay (rather than one permanently mounted to an electronic circuit board) you can change the relay to a more modern electronic version which will cope with LED or filament bulbs...
