3SX Custom LED Gen1 Headlight Conversion

Tired of weak, old, dingy sealed beam lights?

3SX can help!

We offer both the OE-Style and Diamond-Clear Style Glass Lenses:

The OE-Style lenses are for those who want to keep the original look of the headlights, but have the increased output that LED lighting has to offer, while the Diamond Style lenses offer that custom, crystal clear look that some drivers prefer...and a touch more output

 These are sold in pairs, so you get both needed to install!

NOTE: These can only ship to the 48 States, No International or HI/AK/CAN Shipments

OEM Style:


Bulb Pattern:

(OEM Style, the Diamond Clear need modification to lense and housing bucket)

The 40W LED Light Bulb is equipped with BOTH a Heatsink AND a Silent Cooling Fan to aid in both great light output and LONG-LIFE

Installation Tips!!


1- Some early cars had smaller bucket bores, and the new Crystal Diamond lens might not pass through (See Diagrams A +B Below) 

Easy, 10min or less fix with a rotary tool such as a Dremel, etc


2- On early cars, the OE-Style rubber boots may need to be removed


(optional anyway)

Diagram B


Early Cars may need additional clearancing across the back:



** City Light Installation: Two little blue bulb inside your Crystal lights can be wired up to either your running lights or your turn signal lights. You can also just cut the wires off and leave it plugged. Our light vendors switch up batches on us and some ship with these while others do not **
