Howdy All,
I was hoping to separate blinkers from the brake lights in my FC.
Is it as simple as running new wires from the flasher and installing bulb cups?
In a word, NO.
I assume you mean lampholders (bulb cups).
You will need the original brakelight lampholder to retain the dual filament lamp which has 5 watt taillight and 21 watt brakelight.
If you want to use the lower lens for indicator/reversing, you will need a 21 watt indicator, and probably 21 watt reverse light.
I'm not sure if you can buy a lampholder and globe with 2 x 21 watts.
If you think 5 watts is bright enough for your reverse light, you can fit a normal stop/tail lampholder with a bit of fiddling, but you will still have to run extra cabling from front to rear, and some wiring(connection) modifications are necessary to make it all work.
It can be done, but it's not straightforward
The easiest way is to convert to late FC specs which flashes the amber reversing light.Cheers,
Prof.
