Genuine Grande ones are very very expensive and the major difference is their switch. U cannot install that switch as thats integrated in lights switch assembly. Get regular chinese onese, they will serve the purpose. Quality is pretty ok in DLAA fog lamps available under 6000 pkr.
Fortuner / Facelift Grande has bi beam led lights, not cheap to install or arrange at all. Photum leds are good but any led in a halogen assembly is a pain for coming traffic bhai. Standard bulbs are good, else go for Phillips extreme vision. Avoid all led/hids in halogens assembly..i literally get tired of abusing people blinding others. Projector lights are totally different. U can certainly install highend projectors, if u are good on budget.. @haseeb.basharat. He has customized projectors installed in Corolla
