The Mysore Palace Board will illuminate the Amba Vilas Palace. The beauty of the structure comes alive when over a lakh bulbs are switched on.

ILLUMINATION TIMINGS - SUNDAYS & PUBLIC HOLIDAYS : 7.00 PM - 8.00 PM
The Palace has Seven Entrances, Main Entrance is Called " Jaya Marthanda" to East, "Jayarama - Balaram" to North, "Varaha" and "Ambavilasa" to South. Public Entry is from Varaha Gate and Ambavilasa Gate.

The exteriors of the palace are illuminated with nearly one lakh electric bulbs, and the whole palace looks like a fairy tale setting. In fact, the first attempt to illuminate the palace was done as far back as 1878 to mark Chamarajendra Wadiyar wedding.

Mysore Palace is probably India’s only illuminated royal structure and is a major tourist attraction, especially during Dasara where millions of tourists come from far and wide to see the lit up Palace.
The red light atop Mysore Palace in the central dome is used to synchronise the timing of lights from all the four stations simultaneously.
This red light, earlier, was an indicator of the presence of Maharajas inside the Palace. 15 minutes before illumination, the red light is switched on and switched off after 13 minutes. This is an alert to all station workers. Two minutes later when the red light is switched on again, the Palace is illuminated.
