Problem: Fog light conversion to LED

[ADDvanced]

LEDs still generate lots of heat, focused on the back of the bulb area.

I’m looking for non-ballast installs. No HIDs. Cooler LED bulbs would be ideal for me. Just for DRL purposes. The fogs for fogsakes are not vey good to begin with

I run my fogs tilted up a bit as DRLs and they are on for hours at a time. Heat has never been an issue. Used at the factory angle As fog lights they are Perhaps better than nothing. Also I have only replaced one bulb in two years. If changing to LEDs creates effective fog lights that would be a real benefit. If it is strictly for looking cool, go for it. I really don’t see any real problem here though.

Interesting, Gents.

My 35w H3 incandescents run pretty hot. Like I mentioned, I use ‘em as DRLs (so they’re on all the time on my daily driver 3.2).

Well, I welcome all mentioned alternatives or options. Just trying to stay cool

Cheers all

Btw: is there a way to tilt them upwards? It only appears to me that they can be adjusted sideways. I’m referring to stock fogs for ‘84-‘89 (which I think would be different than the SC fogs that hang as opposed to being inset into the valance for 84-89 cars).

Hi everyone! I wanted to make my ‘85 3.2L more visible, so I converted my fogs to DRLs but had concerns about heat and also wanted LEDs to improve efficiency. I tried the H3 bulbs from Diode Dynamics but they were too dim for a DRL. I found these from www.hidkitpros.com by a company called Lumawerks. They’re even made in the US!

I had to do a little filing to turn them 90 degrees from their intended orientation so the LED points toward the reflector properly and am happy with them. At $60 a pair they’re not cheap but also not exorbitant. Good company, nice product, and they fit. You can see that the LED is positioned at the proper distance from the base to basically be where the filament in the halogen bulb was.

Good luck!

How are these working out for you? Visibility in the sunlight? I am running my stock fog lights as DRL and if you have any information on how you "modified" these (filing?) it would be much appreciated. Price seems fair and good to see made in USA.

Thanks for your original post -

Hey, thanks just gently filled the same shapes into the H3 flange at 90 degrees to their original location. Took ten minutes. Pardon the bad markup.

[Mason_paul]

I haven’t driven the car yet this year due to the lockdown...but their brightness was similar to the halogens in my garage.

This is what SPOKE (Jerry) made for me

[Harpo]

Yes, the heat sink fits inside.

I’m also running Spoke’s custom LEDs for Fog lights in my ‘87 Carrera.

[Mason_paul]

Those are sweet. Didn’t know they existed. Does he still make / sell them?

[Rleog]

Definitely

[Mason_paul]

Those are definitely super cool. Bit more expensive than the bulbs I’m running...may try a set when the world starts turning again...

Thanks!

I’m running Spoke’s fogs on my 914. Like all his other products, they are great. Any trouble, he’s a real person who responds promptly. I haven’t had any issues.

[Mason_paul]

I try to do likewise...Good to hear from you again Mark!

I got an email yesterday saying the supplier (for the heatsinks) can now fill all orders although there is likely a backlog with military/essential businesses getting preferential treatment. When I get confirmation of shipping I'll remove the "out of stock" condition on the foglights.
