Ain't it the truth!

On my 64 Chevy Van the turn signal switch was broken and the cost of
replacement was beyond what I had budgeted at the time.  As the van came with 
dual filament bulbs I left those in place for use as brake/tail lights.  I 
added a pair of amber lights below the existing red lights and connected them 
to the turn signal flasher by means of a single pole double throw switch.  
Now I have red tail/brake lights and amber turn signals.
