I don't think anyone can be happer than I to see Klingons with blue headlights!
Depends on where you go for your information: According to Canon, yes, klingons have photon torpedoes. According to SFB (which I actually like more) klingons had Disruptors instead of photorps, and used phasers along side them (basically everyone had phasers whereas disruptors are a heavy weapon analogous to the photorp). In my lore Klingons used lighter beam disruptors as primary and heavier pulse disruptors as heavy weapons with no photons whatsoever.
I will agree for the layout with maybe alittle exception. It has been stated that Ph-1's and such have been used for other weapons (Tholians were stated to not actually have Ph-1's but they are similar). Thus the Klingons could use Disruptor beams for main weapons, but the damage chart is similar to phasers, and the Disruptor bolt as the heavy. Thus the color of the beams are different.
I've come to see the difference between "phasers" and "disruptors" as the difference between AM and FM radio. The weapons would effect subspace, but transmit energy in different wave forms. This way, the Feds can call their specific weapons, "phasers," and use the catch all term, "disruptors" to describe everyone else's. To a StarFleet engineer, the difference would be significant, but for game purposes, they are exactly the same thing.
As far as Klingon torpedoes and "phasers" both being "disruptors," this subject always gives me a headache. I've come up with some varous explanations, but cognitive dissonance seems to work best.
