high mount stop light bulb size

[gsCrazy]

hey guys,

does anyone know where i can get the 921 bulb in 5 watts? my high mount stop light bulbs went out (2 of them) and i replaced them with 194 seeing how they look the same but i still get the bulb out warning. so, i went to look for the 921 bulbs on line but it seems they only come in 17 watts or higher. our lexus manual states that we need the 5 watt 921 bulb.

also, the 921 bulb seems to be wayyyy too big to fit into the high mount stop light. i've also searched and it seems that someone found that the high mount stop light uses the 2825 bulb as per post 1.
