Do not spend extra money to get the light!
The light has never worked properly.  It worked the first day and I sent an email for help.  They asked me to call and he was pleasant and helpful on the phone.  Told me I had to take the battery out and scratch it with my finger.  This worked for just that one night.  I sent another message saying asking for a new light.  They told me it was not part of the lifetime guarantee and I had to call them again- at this point  I had only had it a few weeks.  I don’t have time to fiddle with the battery every day and hope it will work throughout the night and I don’t have time or the energy to call the company again.  Do not spend the extra money for the light - even when it works it doesn’t light up the sign.
