Have a Lionel 38056 M1a and I can only get the cab light (bulb) so far into the socket. Any tips on the install of these bulbs? I installed the grommet first and then tried putting the bulb in, but it's like I can only the 1/3 of the bulb through. Then I tried putting the bulb through grommet and installing the combo but that seemed to be even more difficult. Maybe I just need to try, try again.?
Thank you.
