On the controller in my 300e, I found this small bulb really hard to remove & replace. I used vacuum hose to pull the bulb out. To insert the new bulb I put a straw over the bulb socket, slipped the bulb into the straw so it slid to the socket & put a chopstick into the straw and used it to push the bulb into the socket. Sounds weird, but it worked very well.
Good luck.
Richard
