1975 F250 Instrument Cluster LED Bulbs
 

I wanted to get some LED bulbs for my F250, but I don't know how many or which types. For interior dashboard it has four options, I think there is two main background lights and aren't they the wedge connector type (161, 161LL)? If someone has replaced their bulbs with LED bulbs, do you happen to remember the bulb types? I really just want the background lite up some more, because at night it's a little hard to read.

Just saw this post, so it may be too late. But suggest you make it easy and use these guys. 1961-79 Ford Truck & Bronco LED Gauge Light Conversion Kits - HiPo Parts Garage

They have several levels of kits, and aren't that much more than just buying the bulbs.

I believe the number of light depends on if you have a warning lights or gauges.

Here is a good read. https://www.ford-trucks.com/forums/1...dashboard.html
