Another latching relay?

I'm building a SWAT truck, in this truck the cust. wants "jump lights" (a red and green light to tell them when to go or not to go). I've done this many times before with a single on-off-on switch connected to a single set of lights. BUT in this application the cust. wants 2 independant momentary push button switches with status LED's for both in addition to the actual jump lights themselves controled by a latching relay. So in theory, either of the momentary button/switches can be depressed to toggle the lights to either red or green. This is going the be a 12vdc system including the LED's and lights.  I need alittle help designing this and/or pointed in the right direction to a company that sells these relays to save me some time building this beast. Thanks!
