I am trying to replace my high beam indicator bulb with a blue LED bulb. All places I have searched say it is a 194 bulb, but what seems to line up behind the indicator is a much smaller bulb than a 194. If I could get a picture of which bulb is the high beam indicator bulb, it would be a lot of help. This is my first post, so I hope it is in the right place. It is a 1997 F150 Lariat.

I think most of the indicator lights are 37's. Haven't changed any but that is what I have read elsewhere on the forum.

Different years in the write up, but check out this guide:

Thanks. I will remove cluster from truck and do some further looking today.

For what it's worth, the high-beam indicator is a 37. Kudos to 54-3100. Have a blue LED on the way. Who knows...blue illumination may be next.

If you want blue backlighting, you'll need to remove the green film on the back with chemicals carefully. Either that, or get a custom face with a blue backing. I had one, and while cool... it didn't play nice with my eyes. Navigator gauge clusters are a great alternative. Green lighting also, but white needles with a couple nice extras. Much easier, and no need to pull needles. Swap PCB's, and mileage plus PATS info will transfer right over.
