Compairing the RECO gate light I have with NEG's gate light, the only major differences I see are that the plugs (or are they sockets?) on the sides of the lights are lower on the NEG ones than on the RECO ones and that the NEG ones say NEG on them.

Here's a few photos of my RECO gate light for comparison. This one's incandescent, but the LED RECOs don't seem to have changed at all (other than the obvious difference that the LED ones are LED, of course).
