Increase the brightness of the TE_DLIGHT
Code:
#define TE_DLIGHT 27 // Dynamic light, effect world, minor entity effect
// write_byte(TE_DLIGHT)
// write_coord(position.x)
// write_coord(position.y)
// write_coord(position.z)
// write_byte(radius in 10's)
// write_byte(red)
// write_byte(green)
// write_byte(blue)
// write_byte(brightness)
// write_byte(life in 10's)
// write_byte(decay rate in 10's)
