CHP Headlight flasher
 

Finally got it figured out....heard about the "Streetsweeper" flashers, but couldn't find one. Here it is...I also updated the CHP resto document with a pic of it.

Good find Mike keep up the good work!!

:2thumbs:

Mike, I saw a picture of one of these a while back...do you have the actual unit in-hand? Any idea if that company is still around?

Yet another flasher was also used, the Road Runner ETRR00-P from Sound Off Signal:

This photo from an '89 CarCraft article shows it installed on the coil cover of an in-service '88:

All the indentical mounting and wiring holes for this unit are also present on the coil cover of my car. I'm not sure what other years used this one but I'm checking on the retired '88 EVOC car too as it has much of it's original equipment still intact.

Both companies (ATI and ETI) were merged to form Sound Off. Then Sound Off purchased signal vehicle products (aka southern vehicle products) to form its current name Sound Off Signal. The Road Runner is still made and would be correct for a CHP SSP.

Very interesting Charles. Here's a photo of the Road Runner from the current Sound Off Signal catalog:

Interesting photo. The Unitrols were used early on, and the Streetsweepers later (per the '92 Motor Transport Manual). Maybe these were used for a few years in-between?

Considering what Charles presented, the order of use that makes sense to me (from early to later) is:

1. Unitrol
2. Streetsweeper
3. Road Runner

I'll bet the '92 MTO manual was just using old terminology for the device.

the manual (page 13) shows a picture of the street sweeper (drawing has the same shape and "tab" on one end.) wire color designation is the same a the SS model. I need to find the correct unitrol for my 82 though....

EDIT: "for some SSP cars":o
