Yes, you can replace a 12V MR16 halogen bulb with a 12V MR16 LED bulb, provided the LED version is compatible with your existing transformer. Both use the same GU5.3 two-pin base, so installation is simple, but transformer compatibility is key. Some older magnetic or electronic halogen transformers may not deliver stable voltage for LEDs, causing flicker or reduced lifespan. To ensure optimal performance, choose LED MR16 bulbs labeled as 12V AC/DC compatible, and if needed, upgrade to an LED-rated driver or transformer for efficient, long-term operation.
