You don't have to buy a special flasher unit, just use a resistor to kid the indicator circuit it's got ordinary bulbs.

at 12v a 21w bulb takes 1.75 amps, 2 take 3.5 amps, so you need 3.4 Ohm 50Watt resistor. 3.3 or 3.9 ohm are the nearest preferred values. I'd go for the 3.9 (3R9) resistor as the LED lamps will still take some current.

If you can't get a resistor then connect 2 12v 21w bulbs in parallel
