Just be careful of which wattage you select.
A 55w globe at 12v will draw 4.58A.
A 65w globe at 12v will draw 5.41A
A 100w globe at 12v will draw 8.33A
Where most wiring in a car is not rated above 7.5 amp for continuous operation.
If you exceed this the wiring will literally melt and cause some very serious issues.
Also remember the higher wattage the more light but also the more heat generated.....which leads to more melted wiring, plugs and plastic headlights.....
