Garage Remotes Not Working Properly?

My garage remotes do not work when the light is on. After the 4.5 minutes and the light goes off it will work! Someone posted to change the bulb because it could be a lead bulb that is flickering! Are they talking about the garage fulorescent lighting with the 2 fluorescent bulbs or are they talking about the 4.5 min light to the garage system? I changed the one in the system, but not in my garage because they are very high up. The opener on the wall works just fine.
