Idiot bulbs replacement

Hi guys, does anyone know how to replace the neutral or oil bulbs? mine seem stuck from the bottom and too deep to reach from the top.. it’s probably not be the real problem on my new 84 FE parts bike- but they don’t work, so thought I’d check them. cheers

Don’t worry, they come out the back like usual- probably never touched since new, so had to use CRC and gently twist and pull with a pair of pliers until they moved. they were just old and stuck in good!
