There's two reasons why aftermarket looks brighter in terms of light output. One is that they use D2S bulbs which are meant for projector headlamps, so putting those on our reflector headlamps will produce all that glare, making it look a lot brighter. The other way is using 55watt bulbs instead of OEM 35watts, but you will also need to switch out your OEM 35w ballast for an aftermarket 55w one. However I wouldn't replace our OEM set up for an aftermarket one.
