Mounting resistors

Hi All

I'm using a few (five) LED warning lamps / rear fog lamp and, as these aren't 12v fittings, I need to fit resistors. In the past, I've soldered the resistors 'in line', heat shrinked the fitting and cable tied it all to a straight bit of chassis to stop the resistor from being flexed. I could do this again as it's simple and lightweight but was looking for a more elegant solution. I've considered fitting the 5 resistors into a small project box onto a piece of strip board but this seems a bit OTT for what I'm trying to achieve!

Any thoughts?

Regards

Wyn

your way beats mine, i stuck each end into a connector block and taped it all up into the loom. God knows where it is now!

But i guess yours works!

I bought a handfull of 12v resistors from Maplins.
Not too helpful am I?

i have done this a couple of times once with a project box(bit ott) and my best effort was soldered inline inside a small piece of rigid tube about 3mm inside diam. then i syringed in a bit of liquid rubber, all then heatshrinked. this may be a bit ott also but it worked well

I once made a computerised dashboard for a home-made car - back in the early 90s this - and I wanted an external temoerature display on there. The ntc temperature sensor I got from RS components was a fantastically tiny and delicate thing so I soldered it up and potted it in araldite inside an old biro tube. Then the next day I broke the biro tube off to reveal quite a nice beige temp sensor thing.

The bloody cat ate it. next day there was just a bit of wire left.
I never did have external temperature display....

Thanks guys

I'll probaby go for the simple option of soldering in line as I have very little space behind the dash. I'll keep the cat away as well.........

Solder in line and heat srink

why not fit 12 V LEDs? (maplins sell them in various colours).

Thanks Guys

I'll go for the inline option.


02GF74 - as some of the LED's are in clusters (Maplins again), it's impossible to use 12v ones.
