Whoah...the glow effect works pretty well, there. Definitely an improvement, I think.
Of course, I complained way back when that I didn't think your lights looked bright enough...
The "Glow" is an effect. There are many other ways to get it, too, but the glow effect is easiest.
A word of advice, though...always make a duplicate layer before playing with the glow or blur effects. That way, you can just turn off the backup, but still be able to undo it if you change your mind, later on.
