612 Vermont LED Window Candles replacement bulbs for our VT-9133 electric window candles. Unlike other LED window candle bulbs, our filament is horizontal instead of vertical. This change in the direction of the light source helps mimic standard incandescent replacement bulbs better than vertically assembled units. Our 0.5-watt LED bulbs can be used to replace 5-watt and 7-watt incandescent bulbs used in standard electric window candles. If used in sensor window candles our LED will in many cases still glow dimly due to the design of sensor window candles. Also, note that in some old electric window candles, these LED bulbs may flash on and off for 30-60 seconds.
