Just changed both HL bulbs on my '05...
Left side took about 5 min... quick and easy even with my big paws.
Right side about 20 min as I needed to pull the plastic around the battery (2 pcs) ... then the actual bulb change was quick.
New bulbs were the std Sylvania Xtravision 9003/H4 55/60W units..... old bulbs were ok but of unknown age (I've had bike 18 mos) so I changed them.
