Jeep Indicators

Standard amber 7440/7443 indicator bulbs for Wrangler JK/TJ models cost R80-R150 per bulb at most auto parts stores. LED upgrade bulbs run R250-R450 each but last longer on Johannesburg's potholed roads. Grand Cherokee WK2 LED indicator units are dealer-only parts at R1,800-R3,200 per assembly.

Hyper-flashing on Cherokee KL or XJ models means a bulb has blown, reducing electrical resistance in that circuit. Replace the faulty front or rear bulb (R80-R150) and the flash rate returns to normal. If using aftermarket LED bulbs without load resistors, this causes the same rapid blinking issue.

Older Wrangler TJ and Cherokee XJ models allow lens-only replacement (R350-R650), but Wrangler JL and Grand Cherokee WK2 use sealed assemblies requiring full unit replacement (R1,500-R4,500). Aftermarket options from brands like Depo or TYC offer savings of 30-40% versus genuine Mopar parts at Jeep dealerships.

Yes, Grand Cherokee WK2 and Cherokee KL mirror-mounted indicators suffer water ingress failures, especially in Cape Town and Durban's humid coastal conditions. Replacement mirror indicator units cost R800-R1,400 each, and it's recommended to seal them with silicone during installation to prevent repeat failures.

Complete indicator failure on Wrangler JK/JL typically means a blown 15A fuse in the dashboard fuse box or a failed flasher relay module. Check fuse F87 first (costs R15), then test the flasher relay (R180-R350) which plugs into the junction box behind the glove compartment on most models.
