You have EURO lights because you are from PERU, you dont have Department of Transportation (DOT) garbage lights like us in the US have.

Your headlights take most likely H4 bulbs. I run 100W high beam and 80W low beams with no problems. they are called 100/80 H4 bulbs. PIAA makes bulbs, but I dont like them. THey claim to have a lot more light, but they wrap the coils in the lights less tightly so it makes it appear brighter, but they really arent.

I buy OSRAM/Sylvania lights typically. Narva is a good brand too. Try the wattage range I recommended. If you already have 100W/80, try to get some high performance ones. YOu can get HID kits like holson suggested. THey are about 500 US DOLLARS.

Good luck,

Austin
