TSAL Circuit Diagram

TSAL for a go cart

components:-
1) six white leds which will be covered with red transparent plastic cover or red leds can also be used.
2) 1k ohms, 15 ohms, 2.2 ohms,
 two 10k ohms resistor, 5.6k ohms 1watt resistor
3) hf41f/5-hs relay
4) electrolytic capacitors- 22uf 16v & 470uf 16v
5) 10nf ceramic capacitor
6) ne555p timer ic
7) 2n2222a npn transistor
8) rm9003b led driver ic
9) screw connectors

LED driver formula -   

i(current through led)=0.6/r

r is the resistance value connected between cs pin and emitter pin of 2n2222a transistor in above circuit diagram.
