Halogen Traffic Advisor With 4200

[Derek W]

Would it be possible to use a Whelen TA837A with a 4200 non-dl and use the built in t/a function without overloading it. Each bulb is 20 watts so at 12 volts that's ~1.7 amps. I dont believe it would be too much for it but I'm just double checking before I hook anything up and cause problems.

May be ideal to solid state relay it.. Also the fact it's halogen the flash patterns may not look good due to "ramp up" of the halogen filament.

You should be fine without using relays. The TA outputs are rated at 3 amps each.
