As Alan said easy enough to access globes.....H4 60/55 are the way to fly, any of the German globe manufactures are the way to go......Osram, Phillips even the top shelf Narva. Keep under 4000k colouring.
In halogen above 4000k is rare and may look funky but you are losing light distance/penetration?
You can go the rings as recommended or *carefully* trim the bottom 2 tags on the globe and locate into the holder
My 2 cents
