Greetings Everyone,

 One of our members was looking for some ideas for police vehicles with working lights and the best place to purchase said lights.  Well, here's a bit of my handy work and where I got the lights.   It's hard to see because of the over saturation of the white LED's (and the fact that I used a cheap camera with video function), but the light bar has a total of 6 "strobes" ( PICO Flashing Chip LED's).  Two of each, red, white and blue.  There are blue "strobes" mounted where the driving lights go along with two red "strobes" for the tail lights.  Finally, two 3mm warm white LED's for the head lights.  Unfortunately, there wasn't enough space inside of the vehicle for the power supply so this vehicle will have a tether to a fixed power supply under the layout, (whenever I get around to actually building a layout).  For the purpose of display, the cruiser is temporarily connected to a 6 volt power supply which consists of 2 #2032 coin cell batteries in a holder with a switch.  All of the LED's and some of the wire that was used in this build came from ModelTrainSoftware.com, also known as Evan's Designs.  They are great to deal with and they are a forum sponsor as well (win, win).  I have posted a video of the completed model.

Looks great. I think you did a fine job on it. I want to try one of these someday too, but haven't done anything this small. A fire engine would be great too. My grandson had a Lego Mini Cooper that we put a light kit in last summer, he wanted lights in it. It was a lot of fun, but also a lot larger. 

Howdy Rrtr,

 Thanks for the kind words.  And yes, it is quite small.   The truth is that my Tri-Focal glasses got a little help from my  OptiVISOR Headband Magnifiers.   I also have a magnified jewelers lamp if needed.  The PICO Chip LED's are about the size of the head of a pin and the wires are about .007" in diameter (which is about 2 to 3 times the size of a human hair).  It's a bit of a challenge but the finished product is well worth the effort. 

 

Thanks for the kind words guys.   I got the idea for the front strobes from the Ohio State Trooper cruisers.  The Ohio State Trooper cars have red "strobes" in the grill as well.   I think I'll be doing one of the OH Trooper cars in the near future and I'll try to adapt the red "strobes" in the grill too.

Hi Craig,

Total cost of the completed car (including the car which has 10 Flashing PICO LED's and 2 warm white LED's for the headlights) is roughly $62.00.  Then there is the time and equipment involved as well.  Working on the project sporadically I would estimate 3 to 4 hours.  That time included disassembling the model without breaking anything (not as simple as it would seem).  Also, all of the overhead mounted LED's had to be disassembled as well.  This entailed removing the shrink tube protecting the flasher circuit components (these are VERY delicate and extreme care must be taken here).  Once the shrink tube is successfully removed, the wire leads must be De-soldered from the flasher circuit so the wires may be routed through the roof using the smallest drill possible and then Re- soldered back onto the flasher circuit..  These wires are approximately .007" to .010" in diameter (about 3 times the thickness of a human hair) and are difficult to work with without some type of magnification.  I regularly wear Tri-Focal lenses and I supplement these with OptiVISOR Headband Magnifiers AND a Jeweler's Magnified Lamp while I worked on this project.  A pencil tip variable temperature soldering  iron is highly recommended as well.  I first saw a display of vehicles with LED's installed during a trip to York and when I saw the price I thought they were expensive.  However, after building one of these myself, I realize the REAL cost involved.  BTW, I forgot to mention various adhesives necessary and a good (variable speed drill or Dremel tool) are "Must Haves" as well.  Oh yes, did I mention that the patients of a Saint are helpful too.

Yeah that sounds like a real big project, thanks for sharing the details, I was trying to get an idea of the DIY price versus the guy at York.

I did notice the OGRE group that advertises here has a vehicle upgrade kit (includes headlight and tailight LEDS) $14.95 per car plus shipping. That seems pretty reasonable.

I believe the OGRE kit is just headlights and taillights without any flashing.  This is OK for Non Emergency vehicles.  Give em' a try.

I got one of these a couple years ago. Hakko FX-888D I think a lot of folks here use the Hakko's. I picked it from reading their posts. Some have the more expensive versions, but the FX-888D is a very nice one for the hobbyist, works great.

I got one from Amazon that included an assortment of tips, but the pencil point tip and small chisel tip are about the only ones I have used so far. Seems like it was around $125-$130 with the extra tips or maybe $90-$100 without them.
