12 Inch LED Light Bar - Part Number: LEDST-X-12-4L
The STEDI ST-X 12 inch LED light bar uses 4 x 15W LEDs behind hooded reflectors. STEDI is clear about its purpose: this is not a near-field spread bar but a long-range driving light, built for highway and high-speed touring where mid to long range visibility matters most.
The controlled vertical spread cuts glare reflected back off high-mounted road signs, and a built-in LED parking or position light function, in amber or white, gives the bar a running-light look when the main beam is off.
The housing is finished in anodised polyester powder coat, with a breather that equalises pressure through rapid heat-up and cool-down cycles. The bar is IP68 waterproof, shockproof and UV shielded, with protection against reverse polarity, voltage and current surges and RFI/EMC interference, plus pulse width modulation thermal management.
