These say they are dim-able, but they don't adjust like the originals. I installed them in my gauge cluster and they are bright, or off....

To dim LED's, you need a PWM dimmer, something that the factory does not have in these trucks.

I just finished up the front of the truck.
The side marker lights took the WLED-AHPS: Amber $5.95 ea.
and the front marker lights took the 1157-A27-T: Amber
The center dome light looks great with the 4410-CW8: cool white $4.95

Where I screwed up.... I ordered the wrong bulbs for the tail and turn lights.
I'm pretty sure they should be the 1357 LED 18 SMD @ $12.95 ea.

So....no easy way to make these dim in these trucks then?

To dim LED's, you need a PWM dimmer, something that the factory does not have in these trucks.

To dim LED's in the dash, radio and heater controls you need one of the following.

You need to isolate the illumination wire and the ground for all of the circuits you want to dim. ( Cut, splice, solder, etc )

Connect both the positive and negative to the PWM dimmer.

Find a place to mount said dimmer.

OK, Thanks Michael. I'll add that to my list.

So, Superbrightled said that for my 95 I should use the 3157-R27-T-CK red for the rear taillights.
I'll also need a RL-650-K load resister for each bulb...

This gets confusing and expensive, but they sure look sweet.
