I had to go back to 2008 but I found my post on light bulb site. http://www.memotronics.com/ . This site has lots of lights and if you need to replace them it is a great place to find replacements.
I have a different base for the lights in my car but what I did is look for lights that had that base and then find the wattage after that I could look for higher wattage bulbs. Keep in mind that the higher the wattage the more heat and plastic will melt if you increase the wattage.
The 1895 bulb is a 14 volt 3.78 watt lamp. So I would think that you could go as high as 4.0 to 4.5 watt lamp without much risk. Does a light bulb like that exist ?? do not know you would have to try some different numbers or maybe call out "BA9s" bulb base and search Google to get some numbers then use this site to get the voltage and wattage ratings.
Any way if anyone is ever interested in light you will want to copy this link.
By the way some sites only provide amps and volts so this is how you figure watts (amps x volts = watts).
I did a quick search on the web using the "BA9s" found this #293 MINIATURE BULB BA9S BASE - 14 Volt .33 Amp G4-1/2 then calculated the wattage which is 4.62 watts.
Now if you want to figure out what the light increase would be go to this site http://www.rapidtables.com/calc/light/watt-to-lumen-calculator.htm
In this case the 1895 is 56.7 lumens and the 293 is 69.3 lumens or about an 18% increase in light.
And best of all Memo Tronics has a box (10 ea) of 293 for $2.29 he ships small things through the mail so it should cost may be $0.60 for postage.
Hope this helps
