Thomba48 Posted September 19, 2018 Report Share Posted September 19, 2018 I know. A very essential and important question that I am raising here ?. I know. But interesting to me nevertheless. (is also an indication for the fact that the big tasks are getting fewer and fewer, finally). This is an underhood lamp similar to the one displayed in the accessory folder for our Plymouth. https://www.ebay.com/itm/1930s-1940s-1950s-Chrysler-Dodge-NOS-MoPar-Plymouth-DeSoto-UNDERHOOD-LAMP/362162480096 Where would that be screwed to? A picture would be nice ? Thanks/ Thom Quote Link to comment Share on other sites More sharing options...
desoto1939 Posted September 20, 2018 Report Share Posted September 20, 2018 I would say that this type of mercury lamp would have to be install on the allegator style hood and not on the side opening or butterfly style hood. i have a factor mopar under hood lamp for my 39 Desoto that mounts onthe firewall and there isa rod that pushes the lamp down when the butterfly hood is closed.

Rich Hartung Excellent, I have the same push-down model. Where on the firewall did you mount yours? The horns seem to be in the way. Photo maybe?

T120 Posted September 21, 2018 Report Share Posted September 21, 2018 The under hood light Rich mentioned is probably the same as fitted to my 48 Dodge D25 (alligator style hood). The MoPar Part No. is 1232607. Although the box shows side opening hood, this light was supplied when the car was delivered to the original owner.The cost as listed on the original invoice was $1.75. The lamp is spring loaded and tilts up when the hood is raised as shown in the photo. As per the instructions, the position of the lamp is the same for both types of hood. I cut the wire to the lamp as the insulation was deteriorated. It wouldn't be difficult to replace the wire, but these days I require a bit more light than this lamp would supply when I'm working under the hood.?

Picture on box seems misdrawn, or did they shorten the rod? Anyway it can't sit in the middle like yours. Light will only be on left side. Thanks for the photos.

T120 Posted September 21, 2018 Report Share Posted September 21, 2018 This is the installation instruction sheet for the under hood lamp. It does mention position of the lamp on the firewall on the oil filler side and adjusting rod length as required....

T120 Posted September 21, 2018 Report Share Posted September 21, 2018 Something I should mention is that I would not recommend buying one of these under hood lights expecting it to work. The chances are very good the mercury switched lamp socket is no longer working. The lamp would have to be modified using a different socket and perhaps a manually switched, fused supply.

Plymouthy Adams Posted September 21, 2018 Report Share Posted September 21, 2018 given the lamp works with the mercury switch...location will be based on the angle of the hood when open fully for best access for maintenance. The distance to the area you wish to shed the most light should be centered on the distributor...mount so the beam focal point will be there...you will automatically get a ever widening beam as it travels further from the bulb/reflector. Point maintenance is usually the most common check under the hood followed by oil which is by the way, right at the distributor Quote Link to comment Share on other sites More sharing options...

Yes this is the under hood lamp that I was talking about. i have a NOS one in the original box like that is shown and a non working lamp becasue as you have stated that the mercury might have dried up/ Rich Hartung Desoto1939@aol.com 1 Quote Link to comment Share on other sites More sharing options...
Thomba48 Posted September 22, 2018 Author Report Share Posted September 22, 2018 I did follow this all with interest. I will look around if I find this type of lamp over time. Obviously not something that is just lying around on the shelf somewhere. Thanks Quote Link to comment Share on other sites More sharing options...
Thomba48 Posted September 22, 2018 Author Report Share Posted September 22, 2018 (edited) By the way I found a guy in Calgary. He still selling two NOS ones for 65 CAD each. Thom Edited September 22, 2018 by Thomba48 Quote Link to comment Share on other sites More sharing options...

Thom As I mentioned regarding N.O.S. under hood lights of this type...Chances are the mercury switched lamp socket is no longer serviceable and the light won't work as designed Quote Link to comment Share on other sites More sharing options...
Thomba48 Posted September 22, 2018 Author Report Share Posted September 22, 2018 Hi. It is not the mercury but switch model Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted September 22, 2018 Report Share Posted September 22, 2018 excellent...buy one, mount it and show us the pictures.....if manual switch...suggest a pilot light so you know if you accidentally left it on when you close the hood.. 1 Quote Link to comment Share on other sites More sharing options...
