Spanish While Working

I was working on my truck last weekend.  I was installing lights on my roll bars.  I looked at the switch that my stepdad bought for me, and I saw that it had spanish translations on it.  So, I tried to test my spanish skills before reading the English even though I already knew it was a switch.  But, from reading the spanish, I found out that it was only supposed to be used for lights.  I was impressed at how good I got at spanish over the last year and a half.
