Older Legacy diesels I have bought, like the GP-7, came with warm white LED headlights that look like incandescents. The new Lionel Legacy diesels I have bought - an F-7 and a GP-35 - come with 'cool' white LED lights.
I think the older warm LEDs look better, and the mismatch looks odd when MUing older and newer locos together. Has anyone replaced the LED on a recent Legacy diesel with a warmer LED?
