I had two old Dillon 450's that I updated to 550's but at age 66 I was having problems seeing the powder in the shell so I went a huntin' and found a light system for the 450 and 550 called UFO's. The lights go along the frame and not the head and do a really good job. They are available on EBAY and are easy to install. I would encourage that you watch the video's a couple of times prior to mounting the systems.
- I did have some minor problems with them sticking, even after doing what they suggested but a little rubber cement and they are stuck.
- The light strip part that goes down the front of the frame needs to angle from right to left (as you face the press) or the wire detents on the plate will slightly touch the wire.
- I do recommend this system because you cant believe how bright they are and they come with a lifetime warranty (This warranty does not mean as much to me at my age as it would say if I was 30 again!).
- With one Dillon set up for Large Primers and the other set up for Small Primers I needed one whole set and one expansion kit.
