Has anyone converted their headlights to h4 bulbs? The h4 bulbs mount in a h13 housing and many companies make plug adapters to convert from a h13 plug to a h4 plug. I want to upgrade to a higher wattage off road hella bulb, which isn't available for h13 bulbs. Does anyone think the stock housing could melt? I'm thinking about running 55/100w hella bulbs. I would upgrade the wiring harness so I wouldn't melt the wiring, but I want to make sure I wouldn't melt the housing.
