This may be counter intuitive to your brighter lamp request, but 850's are famous for blowing instrument, switch and console bulbs frequently. After the first few years of ownership (original owner) and getting tired of replacing bulbs all the time, my mechanic gave me a tip to prevent further bulbs from blowing. Just take the dimmer and lower it from say 100% brightness to 98% brightness. You won't even know the difference. After 13yrs of ownership, we haven't replaced an instrument bulb in over 10yrs. True!
