Auto electric question

[DAVE77]

Ive just fitted some LED indicators at the back of my car. Now the thing is my indicators flash too quick (as if theres a bulb not working). Is it possible to get a flasher unit from a car without side repeaters (only 4x lamps, not 6), or can I get a resistor to make up the load of a 21watt bulb?

Im thinking of fitting LED bulbs to all of my indicators.

Im not an expert but Im sure you could make up the load with a resistor. Youd have to research the maths to work out what resistance you need but this site might be some use:

Well if you wanna simulate the load then calculate the current first then the resistance. So P=IV, I = 21/12 = 1.75A

Then if V=IR, R=V/I= 12/1.75 = 6.85 ohms.

Hope thats right, Im a bit rusty!

Or you could just put another indicator into the circuit and just hide it somewhere amongst the wiring where you cant see it?
