Better to stick with stock specs. in Electrical items.
High Light could be dangerous if not installed with attention. If you r planning to change then whole path should be revised.
Whatever maximum current your 55 watt or 90 watt Bulb draws,
Fuse and holder should be 1.5 x ampere rating of bulbs
Wire/cable ratings should be 2.6 x ampere rating/ drawn of Bulb
E.g For for 55/60 watt bulb, ampere drawn maximum will be 5 Ampere so holder and Fuse should be of 7.5 Ampere(12 Volts) while Electrical wire rating should be 13 Ampere(12 Volts)
