Hello, Im new here and have been reading a lot.
I just acquired a 78 DT400. It needs all the lights reinstalled.
I don't have any of them except the headlight.
Where do you all go to for this kind of stuff? Ebay? or???
I want to get it back on the road as it runs great.
Thanks

Ebay is your best bet...but your local Craigslist might also give you hope. There are various motorcycle graveyards/boneyards around the country as well. Google vintage motorcycle parts, and see what's in your area. There is a classifieds section here, I think, and there are several members with large inventories of NOS parts, too. Post exactly what you need, and you may get a good response.

For turn signals the rear part no. is k&s technologies 25-4015, and not 25-4016 which is what the parts catalog from k&s specifies. It is incorrect- and the front is 25-4155. There is an oem part that you will need if you dont have in order to make the rears work. It is part 15 in the schematic below. Also the mount bracket for the front turn signals from k&s looks cheap, but is still available from Yamaha part no. 7 if you want to be a purist on that.

I believe that the rear brake light bracket will only be found used.

Here is a tail light new in aftermarket


You will need all those dampers listed below in the schematics or make your own. Some are available from yamaha. Others not available the best bet is to enter the part no.s on ebay or google to find them. Better would have been to find the complete used taillight/bracket assembly and they do come up from time to time, and some with a fender as a unit.

Ok thanks for the input. I have looked at partzilla and ebay, stuff is available.
But what if I decide to go RetroMod and get a light kit from for instance Baja Designs or
a similar company? Or something like this....
I like the led's and integrated hand turn signals. Would it be easier or harder to go non stock? I plan on using the bike mainly on the street and will get more street oriented tires.

Welcome! That kit would be great to put an IT on the road. I really like the hand guards with TS. I 'm all about visibility. I go for originality up to 76, after that, go for it. Lots of answers here. Post lots of pics, we love to watch projects in progress.:likey

Challenges with LED's is your bike is 6 volt and headlight is AC powered. Most LED's require closer to 12 volt and DC power.

Not impossible to do especially if you use a modern 12v Powerdynamo ignition.

Other kits have regular bulbs which can probably be swapped for 6 volt.

Ok got it. I sent a email to Rex and he said the same thing. Keep the headlight the same, do

the 12v conversion for the rest of the system then I can run led's for tail and turn and

pretty much anything else I want. Im thinking of going with a dash like this.....

Now I know what direction I want to go. I will start a project thread soon.

Thanks for all the help!

I got this Trail Tech Vapor for free, so I'm putting it on my Bultaco project.

The Black Acewell is very cool looking
