BHPian CEF_Beasts recently shared this with other enthusiasts:Exterior Incandescent to LED Bulbs UpgradeI decided to upgrade all the rear incandescent bulbs to LEDs. The taillight’s brake and parking light are LEDs, but the indicator and reverse lights are incandescent bulbs. Decided to upgrade these to LED, and while was at the job also decided to upgrade the License Plate incandescent bulbs to LED as well. Now the only incandescent bulbs on the exterior of the car are under the ORVMs ie. the puddle lamps.The Upgrades:Indicator Bulbs Specifications : Amber Colour 2000LM & 3000K LED WY21W / 7440 BulbReverse Bulbs Specifications : White Colour 2000LM & 6500K LED T15 / W16W Bulb(Indicator and Reverse LED Bulbs I’ve used are from Autobahn Technologies)License Plate Bulbs Specifications : 2x T10 Bulbs (I’ve used Philips Ultinons)Note: All the Interior dome lights across the cabin, puddle lamps underneath the ORVMs and license plate lights employ T10 bulbs in the HyCross, no festoon bulbs are in use in the HyCross. Ordered a Taparia 1/4″ 46 Sockets Tool Kit alongside the T10, indicator and reverse LED bulbsFor the Reverse Bulbs:The process is fairly simple, open the tailgate and you’ll see 2 cut-outs in the boot trim, just have to pry them open with a flat head screwdriver to access the bulbs. Rotate and unlock the bulb holder after which you just need to pull out the incandescent bulb and insert the new LED bulb. Make someone switch on the car and shift to reverse to check if the LED bulb lights up or not. If it doesn’t, it needs to be rotated 180 and re-inserted since LED bulbs have polarity. Simply twist the bulb holder and it’ll come out with ease Pull out the halogen bulb and replace it with the LED, test the polarity by shifting to reverse, otherwise after installation will have to do double the work Halogen Bulb that was removed on the left and Autobahn Technologies 6500K & 2000LM LED Reverse Bulb Reverse Lamp Before vs After: Halogen on the right and LED on the left Both Left and Right Reverse Lamp bulbs changed to LEDFor the License Plate Bulbs:The lights are covered with a plastic cover with a foam strip to prevent it from rattling with the body of the car. To open these plastic covers, on the outer sides of the plastic trims, there are small holes in which you need to insert the smallest flat-head screwdriver and push the handle of the screwdriver to the left making the head of the screwdriver push towards the right, loosening the plastic trim. The T10 Bulbs just need to be pulled out and the new T10 LED bulbs are inserted, the polarity needs to be checked before re-installing the plastic light covers. Here both License Plate bulbs are halogens The left license plate is LED and the right one is still the old yellow halogen Both license plates replaced with Philips T10 Ultinon 6500K LEDsFor the Indicator Bulbs:The tail light assembly on the body needs to be opened. You’ll require T10 sockets to open the 2 bolts that hold each tail-light. Once the bolts are removed the light assembly needs to be gently slid and pulled out. You’ll see a yellow cap which is essentially the bulb holder, which needs to be twisted and removed. In the same way, the bulbs just need to be pulled out and replaced with LED bulbs. Before vs After: Right has the new LED bulb, meanwhile Left has the halogen bulb. Both Indicator bulbs changed to LED LED Indicators in action with Brake lights All Lights in action: Reverse Lamp, Indicators, Position-light and Brake Light A video to show all the lights in action. The total damage to the wallet to move from Incandescent to LED Bulbs was ~3600. Check out BHPian comments for more insights and information.
