I've read a few threads on replacing the bulbs when clearing out the corners. Some people have used an orange Sharpie marker to coler the existing bulbs. Rick's Accessories now offers the clear diffusers (I've orded a pair by the way), but does not offer the amber replacement bulbs for the corners.

Will these amber bulbs work for replacing the existing 7440 bulbs?

Amber 7440 bulbs

 

Any of those should work.

 

What the hell is hyper-Amber?
