The letters look like a modified ITC Neon



ITC Neon was a phototype era font.

Several fonts use a three line maze design, including Eclectic Crumpany NF.
Ico uses a four line maze design, but it IS NOT THE FONT used to make the letters.
Available from CreativeMarket

Several independently created versions of ITC Neon were published, mostly in the 1990s. All are of rather poor quality.
