No....40A is the rating I use just in case somebody wants to upgrade to true HID's or really high output composite headlamps. I thought about building it as a plug n play but imo it looks too messy. I like to keep a stock "appearance". The headlamps will only draw what they are designed to-no more, so 40A is a safe amount of protection. The relays are overrated for the given application but that is meant to ensure a long life. These are not your general parts store relays however in a pinch you can use one if you had to.
