Replacement Running Light on Roof of H2

[Nielsen]

Where can I obtain a "single" replacement running light for the roof. One of the fastening base tabs broke off and I need to replace it. The amber light in the front center.

i broke my front roof light marker also..so for info, i did alot of searching and gm factory only sells the entire light assembly for 120 bucks. way to much..but there are some aftermarket places that sell the lenses..but only sell them in a kit of 10 for the entire set up..for about 99 bucks..i have yet to find a place that just sells the single lens cap..but if you do..let me know cause i need one to..hope this helps.
