hi fellow tsikoters...

I just bought a 2nd hand corolla small body. my question is i noticed when

i opened the headlight hindi siya agad lumiliwanag. sabi ng friend ko ganun talaga kasi projector lamp. he showed me yung parang ballast na naka

connect sa gilid. so my question ganun ba talaga projector ? ilang watts ito

usually? mas malakas ba ito gumamit ng battery compared sa halogen ?

sa mga nagpakabit ng projector. is it necessary to increase amp of your alternator?

thanks
