electrical - Can I install a light between two three-way switches ...

No. The lights can only be controlled by the common terminal on one of the switches. Connecting the light to one of the travellers, will cause it to only be controlled by a single switch. ??Tester101? 22 hours ago
The trouble is basically all 3-way circuits use a 3-conductor wire (take a look at some 3-way circuit diagrams). You always need 2 travellers, and so the other wire is either a neutral or the switched hot (and in the case of the light between the two switches, on one side it's switched hot, the other side it's neutral). The only way it would be possible is if you have a 4-conductor wire between the two switches or run a new 2-conductor wire (either between switches or to the new light). ??gregmac 22 hours ago
The other option is to go to "smart" switches, such as Insteon, Z-wave, or UPB. With these, the switches communicate to each other using a separate carrier signal (either wireless or over existing 120V lines). Effectively any "smart" switch/keypad can control any other "smart" switch/bulb/module from anywhere in the house. If you go this way, you'd have to replace both switches with smart switches, and your 3-conductors between the two become hot, neutral and switched. ??gregmac 22 hours ago
