Impressive lights well worth it

I purchased the 7440 led turnsignal bulbs from alla and I'm very impressed at how well they perform they are way brighter than stock and look great they add safety by being very bright I reccamend for anyone that has OEM led headlights with turn signals close to the low beams (toyotas are terrible for it) no additional resistors required as easy as replacing a lightbulb

Insainly bright your not missing these things

Purchased the 7440/7443 amber bulbs to put in my 2017 toyota corolla as I've had issues with people not see my turn signals and almost crash into me with the stock bulbs I put these in and Holy crap these are crazy and there's zero problems with people seeing my turn signal now lol way brighter then stock no need to add resistors or anything just as easy as changing a lightbulb to install I highly recommend these bulbs

Best leds I've bought

I bought 12 lights total 6 for the turn signals and 6 for the break lights since my cars need more then one, one of the boxes came defective and I reached out and they sent me not 1 box back but 2 new boxes and they worked like a charm definitely worth the price if you ask me and they are super bright no more tailgating.
