You can still find pre-digital camera dark-room lights on eBay, but I suspect a lot is old stock. They don't get many stars. I use theatre spotlight gel sheets https://www.ebay.co.uk/itm/106-PRIMARY-RED-LIGHTING-FILTER-GEL-THEATRE-DJ-CLUB-LED-DISCO-18cm-X-18cm-PAR-56/161603599460?hash=item25a0533c64:g:jKQAAOxyBjBTVYey to cover the bit where the light comes out of my lamp. If you wish to set up a channel of port-hand and starboard-hand lights along your drive to aid you when you come rolling home, you can also place little squares of red or green gel over the flat patch leds now starting to appear in daylight-charging garden lights, . It robs you of a lot of light though, and they work best in the summer when you don’t really need them. DaveP
