Careful, at 14 volts it is 1.96watt. Make sure your tolerances are there or you'll be tearing them apart and replacing them. Could you not find 150 ohm at 2 watt ( 2W Watt 150 Ohm 150 R Metal Film Resistor 20 Pcs | eBay ) to be on the safe side? My car tools along at night with lights on at 14 plus volts all the time.
