Light bulb chart

I've n

I've noticed that the 158 bulbs in my dash cluster don't illuminate the dash very well at night. Has anybody found a higher wattage bulb that will work in the place of the 158s that won't fry your dash electrics? Thanks.
168's I believe if this chart is right.
158 is a 3.36 watt lamp.
168 is a 4.9 watt lamp.
194 is a 3.8 watt lamp.
