I have Narva LED Globes in my Fairmont cluster.

But lately the one that illuminates the fuel gauge sometimes dulls and lately sometimes doesnt illuminate at all.

Why would this be happening? Could is be just loose from its terminal connection or something much more sinister?

i'd say its on the way out dude...a bad earth or short shouldnt really just happen intermittently and outta the blue..

I had a similiar issue with mine only was the speedo guage led...it used to flicker intermittently then one night died....

Just replace it only costs a a couple bucks max....see repco or jaycar

Yeah I got heaps to replace it with, its just a matter of repalcing (Im lazy)

aha fkn, just put that lane cluster in.. and one of my blue lights wasnt working

and i've put the whole thing back together...
now i gotta do it all again just for one globe
