Only your Fog lights should be capped, Bulb capping is generally used in the fog lights to help reduce glare. Take a look at your stock bulbs - the end has a coating or covering on them to help disperse light back into the reflector bowls. Low Beams are not capped, your low beams already have a reflector cap in the housing, Headlights typically have this metal cover that hangs in front of the bulb for this reason (directs the light back to the reflectors). In the fogs, when a HID bulb is used, there is no cap, cover, coating, etc on the bulb, Capping Fob bulbs helps direct that light back to the reflectors - and helps to reduce glare. High beams are not capped in the housing, but some have capped bulbs and other don't, Glaring is usually not an issue with High beams, since you will not keep the high beams on when facing on-coming traffic, unless you have Dual headlamps and not Quads, then both the Low and High beam are on a single light bulb and are located in the low beam part of the housing that has a Reflector cap as part of the housing, Bulb will not be capped for those.
