LED bulbs

In the Ferrari 328 dashboard there are 12 units of medium bulbs type bulbs 9 mm. 4W, Ref. Silvania 3893, Philips 12929 and 10 units Type Small Bulbs 5 mm. 1.2 W Wedge Type, Ref. Silvania 2723, Philips 12516. Wanting to replace all these units with LED bulbs Do you know what type of LED purchase?
I ask for the final solution.. Many thanks.

 

You can find all the bulb type in your manual
That number you can use for cross reference for the led,s on e bay I change all of mine plug and play big difference

 

I have a 1978 308:
Keep the incandescent light bulb for the alternator low voltage warning. A diode is inline to bulb. When the battery output is more than the alternator output the bulb illuminates. (Should be still valid for 328 based on wiring diagram)

I had to purchase a LED flasher relay 3 prong and add a ground connection to my relay board for the additional prong on the flasher relay.
The bimetallic type would not work due to lower current draw.

328 uses a three prong flasher per wiring diagram. It would need a LED flasher module for outside LED turn signal lights and the turn signal lights in the dash.

I purchased most of my LEDs from SuperbrightLED website.

 

Many thanks.

Note: You have a 3 prong incandescent flasher relay. You will need to replace with a 3 prong LED flasher relay. Amazon has them. ~ $12. Purchase the Amber LEDs for Yellow turn signals, and Red LEDs for the rear driving and brake lights.
