Ok, This took a month to develop using spare parts I had and quite a bit of frustration.  Many things were learned while creating this circuit.  Actually it could be called 3 circuits there is a 555 timer circuit, a 4017 counting circuit, and a output control circuit all combined just to make 5 lights come on in sequence and stay on.  There may be several other ways to do this same operation  easier but this one actually made since to me, and it works....  The LED light bars are advisable through DIGI-KEY a electronic supplier they are advisable on the web and their prices are pretty cheap.  The part numbers are as follows    RED:   67-1022-ND  Yellow:     67-1027-ND .   These little light bars can be quite confusing, I tried to hook them up in parallel with resistors on each individual LED but when all assembled it made a better heater than anything else and I didn't want to burn down my car so I pressed on for several days.  Finally I thought what if you were to hook the individual LED's  up in series like Christmas lights ?  I did in several ways and finally came up with the final version.  Be sure to correctly wire each individual LED light bar, it is very precise soldering but can be done.   Also...  to put labels an these light bars I got myself  some transparency (clear plastic) paper for the ol' printer and made labels cutting each one out and gluing them to the light bars with silicone.  Here is my circuit.....
