Very good quality relay and wiring
Wiring length is sufficient for biggest of the cars. Installation is perfect, one even may not know at once that an external relay circuit has been added. It is dual relay circuit where two seperate relays control low and high beams respectively. I installed in Mahindra Thar 2022 to power 90/100 W Philips H4 blue vision halogen bulbs and the result is highly satisfactory. Can be used for 110/130 W halogens.

Excellent quality
Thick wires, separate fuses and relays for each bulb, easy installation. Improved brightness even with stock bulbs. Installed myself. Bought zipties to fasten the wiring from hardware shop and applied tape on the old bulb holder to prevent it from water. Feels much better while driving in the rain than before
