Thanks for all the effort you guys have put into this to give us all a cheaper alternative to sequential tail lights.

Well I'm not sure what the numbers are but if you just go in with the list that's already posted, someone will help you and yes for the timer just ask for the one that can handle up to 200 mA.

Okay perfect thanks.

the radio shack timer is the 555CN timer IC.

P/N 271-0284 100k Ohm Micro-Size Potentiometer
P/N 272-1025 10uF Electrolytic Capacitor
P/N 275-0248 SPDT Miniature PC Relay 12VDC @ 10A
P/N 276-1101 1N4001 Micromini Silicon Diode
P/N 276-1723 555CN Timer

P/N 276-148 Dual Printed Circuit Board
8pin socket mount for the IC (don't have P/N on hand.

hope that helps.

Thank you tons. looking at the schematic it seems i need this in quantity:

2x > P/N 271-0284 100k Ohm Micro-Size Potentiometer
2x > P/N 272-1025 10uF Electrolytic Capacitor
2x > P/N 275-0248 SPDT Miniature PC Relay 12VDC @ 10A
4x > P/N 276-1101 1N4001 Micromini Silicon Diode
2x > P/N 276-1723 555CN Timer

1x > P/N 276-148 Dual Printed Circuit Board
2x > 8pin socket mount for the IC (don't have P/N on hand.) also P/N is 276-1995 for this

Am i correct with the quantities?

I checked Radio Shack for the 275-0248 and it does not come up in any of the searches.

Yeah i get the same as well. I just figured i would ask the guy at a store.

8-Pin Retention Contact also known as socket mount
Model:
276-1995

Model: 270-1802 | Catalog #: 270-1802
Project Enclosure (4x2x1")

the nearest one would be
Model: 275-001 | Catalog #: 275-001
12VDC/40A SPST Automotive Relay

Price:
$5.99 which looks like the same in the picture

Get it worked out, add me to the list

Monday update: circuit did great this weekend. I drove my car out of town both days and used my blinker as much as I could. Everything still works great so the 555cn timer is the one to get. Only had one issue, every now and then the BCM will set the blinker bulb out error and start making that side flash fast. Cycle the ignition or just wait a little while and it will come back. Only happened to me twice this weekend but it is kinda aggravating. Ill be installing a load resistor sometime this week to correct the issue but other than that this design was a success! When I get the resistor in and working I will update everyone with a part number and how/where I installed it.

I got all the parts from Digikey cheaper then radio shack total at digikey 30.97 with shipping and at radio shack 40.20 before taxes.
Yeah thanks for the info I would be very interested to see if the resistor did the trick for you.

I ran into that issue a few times too! Other than that I love it.

Also the project encloser's dimensions are in the picture of the packaging: 5 by 2.5 by 2 inches. This is plenty of space for the circuit and fits snugly behind the tail lights

Think there was something else that was for the tail lights that had to have a resistor in line to keep the bcm from sending a error message can't remember what it was just remember that is what they had to do.
